How is 'Haleem' related to the festival of 'Ramzan'?

Haleem is not related to Ramadan. Though people eat Haleem as it is cooked by adding many grains like wheat, different pulses, rice, etc. So, generally, people take Haleems in Sehri or iftar as it is a nutritious food.
Haleem is generally related to Muharram. When Imam Husain become shaheed in Karbala and sacrifices his life with his 72 shaheeds, Yazeed sent Haleem for the Ehle bait and small children of Imam Husain. So, Muslims cook Haleem on the Muharram and invites the people for the salawat of Imam Husain.

There is no specific relation between Haleem and Ramadan. Haleem is a tasty special food. When we do full fasting for 12 hours when we break the fasting, we prefer to take some special food. When we do Ekadasi fasting the next day when we take our food we like to have some special dish. Generally we will make lemon rice on that day. In the same way when Ramadan fasting is going on the people want to have a special dish and the preferred dish is haleem.

There is no such relation between Ramzan and Haleem as such. However, it has turned out to be the delicacy of Ramzan month and prepared only during this holy month. Haleem is tasty as well as healthy at the same time. Since people fast for major part of the day, they need calories to gain back the lost energy and the most healthy way to do that is by consuming Haleem. It is a mixture of grains and meat and requires extensive preparation.

Its recipe varies from region to region and from one country to another. Still, barley, meat, and the addition of some lentils are the core ingredients. It is cooked slowly for almost 7-8 hours and thereby all the flavors originating from spices, lentils, meat and barley get blended. In India, it is prepared only during Ramzan but in Pakistan, it is available around the year.

Haleem is a nutritious dish taken during the fasting days of Ramdan to get the necessary calories during these days.

It has no mythological or religious link to Ramdan. As we also take nutritive and high calorie food during fasts, Haleem is similar one to compensate for loss of energy during fasts.

Different recipes have been invented by the people in different societies and those which are delicious have remained in use for a long time and are then established as a part of that particular festival.

Haleem is noting but a dish of chicken and mutton. The actual meaning of Haleem word is compassionate and patience. If you are non veg. then definitely you know that it takes a time to make any non vegetarian dish. The process of making is lengthy and tiresome. All three Chicken, Mutton & Beef can be used in preparation of Haleem. It is more popular in Hyderabad city. During ramadan haleem started serving. There is a different and lengthy process of making this dish called haleem.

Haleem is basically a dish prepared to bring back the lost energy and zeal due to hard fasting from morning 5 am to evening 6 pm or depending on the saheri or iftaar timings announced by respective mosques across the country. It is advised for those who goes through the fasting to have the Haleem immediately after the Magrib Prayers, so that they can with stand the hungry feeling and loss of energy due to severe fasting in the scorching sun and thus they have to spend another two hours for Taravee prayers there after and finally end up taking dinner at 10 pm. So Haleem is the strength booster specially taken in Ramzan and not prepared in ordinary days. But now a days it has become fashion and wanting by other communities who want to taste the Haleem during all the 365 days of the year and in Hyderabad we have some restaurants serving Chicken and Mutton Haleem whole through the year.

Haleem is a special dish of chicken and mutton. It has no religious significance. As it is delicious in taste, generally this item is used to break the fast during the month of Ramzan by well-to-do Muslims.

People from other communities wrongly associate this food-item with Ramzan or Eid-ul-Fitr.

The dish Haleem is popular in India, Middle East and other parts of Asia. Haleem originates from an 10th century Arabinan dish callled as Harees. This dish, Harees was brought into India by the Nizam (Hyderbad) Army. Restaurants in the old quarter of Barkas in Hyderabad, still serve the original dish of Harees

It is a thick aromatic curry or stew like dish that contains meat, lentils and spices. This slowly cooked dish over few hours is rich in calories and nutrition, that is popular among the Muslims while they break the fast during Ramzan. Hence the incidental association.

Many mouth watering dishes, sweets and lassi is sold in the popular streets of Bangalore, during Ramzan. I think, after a long period of fasting, people would anticipate to have rich, tasty food.

Haleem has not related anything to Ramazan and we can see that there will be people crowded for having this dish. This dish is made of wheat, lentils, meat which is cooked for many hours. During the 6th century, the Persian king Khusrow enjoys the haleem dish very much. In many Arab countries, it is called harissa or harees.

Haleem made its way into Indian cuisine in 1900s, when it was given to the Nizam of Hyderabad's army. Now this an age old tale. Everything that Hyderabadi cuisine is proud of was once a staple of the Nizam's army. Dum biryani, Pathar ka gosht and Haleem etc...;
Haleem is derived from harees. The local spices and cooking techniques, changed Harees into Haleem.
Since Harees was brought in by Arabs, let us see when Arabs used to eat Harees so that we can get an idea about the connection with Haleem. Harees can be a 1000 years old dish easily because it was described in the "Book of Recipes" written in 10th century.
In those days, Yemenis used to eat this dish bland dish as a staple. It was even used as a medicine or a "hospital food" since it was bland and it was very nutritious. Later with Arab invasion of the peninsula, Harees spread out to the whole of the Arabian peninsula and then finally to India. In India, thanks to our cooking style and unique spices, Haleem was born.
So if we trace culinary history alone, neither Haleem nor Harees has any religious relevance. But we have to thank the Hyderabadi restaurants to Haleem's popularity and its relevance to Ramadhan. Restaurants used to serve them saying those were Ramadhan's special Haleem and it so happened that throughout India, we never get Haleem until the Ramadan season.
That was the interesting history of Haleem.
