Set up by Prophet Mohammed hundreds of years ago, Eid or Eid ul-Fitr is to celebrate two days by offering gratitude to the God while indulging in merriment and festal splendour.
It is a day of joy, celebration, colours, giving, blessing and stunning aromas that enamour one's senses irrespective of the fact that one follows Islam or not.
The day begins early on Eid with Salatul Fajr (the pre-sunrise prayer), and in keeping with the Sunnah (traditions and actions of the Prophet Muhammad), dental hygiene is taken care of, followed by shower (Ghusul), dressing up in new apparels (or the best available), and application of perfume.
Eid on the last day of Ramadan month is all about breaking the fast and so a customary morning breakfast of dried fruits before the first prayer is followed by much extravagant delicacies.
Gifts are frequently exchanged on Eid (called eidi in some cultures) with the children ending up as the beneficiaries in most case.
The shopping spree ahead of Eid is also quite common, especially among young girls and the market places throughout the country were busy catering to the demand for newer clothes and jewellery.
Culinary delights of the greatest Islamic festival are also legendary and dishes like the "shemai" or "sewayan" (toasted sweet vermicelli noodles) or the famous "Hyderabadi haleem" (a type of meat stew) grab the centre stage with foodies in the audience.
