Islam is the religion of tolerance and ease. It provides much space to the Muslims, so that they can be generous to themselves and their families in eating and drinking during the Eid days. In this Hadīth, the Messenger of Allah (may Allah's peace and blessings be upon him) says: "The Days of Tashrīq," are the 11th, 12th, and 13th days of Dhul-Hijjah. They were called as such because in these days people used to cure the meat of sacrificial animals and spread them in the sun to dry, which is known as Tashrīq in Arabic. This was their practice during their era. But, nowadays, the meat of sacrificial animals and offerings is available. They are "days of eating and drinking;" so, people should eat, drink, and not observe fasting therein. They should also remember Allah, supplicate to Him, and show gratitude to Him for the sustenance and guidance He has bestowed upon them. The Prophet (may Allah's peace and blessings be upon him) forbade fasting during the Days of Tashrīq. For example, in a Hadīth narrated by Al-Bukhāri in his Sahīh Collection, Ibn ‘Umar and ‘Ā’ishah (may Allah be pleased with both of them) reported: "No permission was given for fasting during the Days of Tashrīq except for someone who cannot afford the sacrificial animal," i.e., to the performer of Tamattu‘ or Qirān Hajj who cannot afford the sacrificial animal. This represents flexibility for the people. In the prohibition of fasting these days and the command to eat and drink lies a good reason. Since Allah Almighty knows that those who come to His House undergo hardships during travel, tiredness because of Ihrām, and self-struggle while performing the rituals, He prescribed rest for them after that, by staying at Mina on the Day of Nahr and three subsequent days. And He ordered them to eat from the meat of sacrificial animals out of His kindness and mercy towards them, for they are the guests of Allah Almighty therein. He also included the people of other countries with them, for they join them in undergoing hardships for the sake of Allah Almighty, like the hard work they endure during the ten days of Dhul-Hijjah, as they observe fasting, remember Allah, and worship diligently, and in seeking closeness to Allah by slaughtering sacrifices and in the attainment of forgiveness. So, they join them in their Eids, and everyone shares rest by eating and drinking. Thus, all Muslims become the guests of Allah Almighty during these days, eating from His sustenance and showing gratitude to Him for His grace. And since it does not befit the Most Generous to let His guests go hungry, they were forbidden to fast these days..
