It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him), he says: I presented myself before the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah, command me to do an action that will admit me to Paradise. The Messenger of Allah (peace and blessings be upon him) said: Observe fasting, for there is no other deed like it. When I came to him again and made the same request, the Messenger of Allah (peace and blessings be upon him) said: Observe fasting.

Narrated by Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him): The Messenger of Allah (peace and blessings be upon him) said: Fasting and the Qur'an will intercede for the servant on the Day of Resurrection. Fasting will say: O my Lord! I kept this servant away from food, drink, and desires during the day, so accept my intercession for him. And the Qur'an will say: I kept him away from sleep at night, so accept my intercession for him. As a result, both intercessions will be accepted.

Narrated from Sayyida Umm ‘Ammarah bint Ka‘b Ansariyyah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) came to her house and she brought food for him. The Prophet (peace and blessings be upon him) said to her:“You also eat.”But she replied:“I am fasting.”Upon hearing this, the Noble Prophet (peace and blessings be upon him) said:“When food is eaten in the presence of a fasting person, then as long as those eating have not finished, the angels continue to pray for mercy for the fasting person.”

It is narrated from Sayyida Umm ‘Ammarah (may Allah be pleased with her) that the Noble Prophet (peace and blessings be upon him and his family) came to her house, and many people from her tribe gathered at her place. She presented dates to serve him. When he began to eat, one man moved aside. The Prophet (peace and blessings be upon him and his family) asked: What happened to him? He replied: I am fasting. Upon hearing this, the Prophet (peace and blessings be upon him and his family) said: When a fasting person is with people who are eating, the angels continue to pray for mercy upon him until they finish eating.

It is narrated from Sayyiduna ‘Amir bin Mas‘ud Jumahi (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: The fasts of winter are a booty obtained without hardship.
