It is narrated from Sayyiduna Abu Huraira (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said:“(In the Divine Presence) deeds are presented on Mondays and Thursdays, and I desire that my deeds be presented while I am fasting.”

It is narrated from Umm al-Mu'mineen Sayyidah Aisha Siddiqa (may Allah be pleased with her), she says that the Messenger of Allah (peace and blessings be upon him) used to fast on Saturday, Sunday, and Monday in one month, and in the next month he used to fast on Tuesday, Wednesday, and Thursday.

It is narrated from Umm al-Mu'mineen Sayyidah Aisha (may Allah be pleased with her), she says: The Quraysh used to fast on the day of Ashura during the period of ignorance, and likewise, the Messenger of Allah (peace and blessings be upon him) also used to fast on this day. Then, when he came to Madinah Munawwarah, he himself fasted on this day and ordered the people to fast as well. Then, when the fasting of Ramadan was made obligatory, only the fasts of Ramadan remained as obligatory, and the fast of Ashura was abandoned. Whoever wished, fasted on this day, and whoever wished, left it.

Imam Alqamah says that I asked Umm al-Mu'mineen Sayyidah Aisha Siddiqa (may Allah be pleased with her) whether the Messenger of Allah (peace and blessings be upon him) used to specify any particular day for worship. She replied: The practice of the Messenger of Allah (peace and blessings be upon him) was continuous. Who among you has the strength that the Messenger of Allah (peace and blessings be upon him) had?

It is narrated from Umm al-Mu’minin Sayyida Aisha Siddiqa (may Allah be pleased with her), she says: The Messenger of Allah (peace and blessings be upon him) came to me and there was a woman with me. He (peace be upon him) asked:“Who is this?”I replied:“This is such-and-such woman, who does not sleep at night (rather, she stands in prayer).”The Messenger of Allah (peace and blessings be upon him) said:“Adopt only those deeds which you are able to do. By Allah! Allah does not tire (of giving reward), but you will tire (of performing deeds).”Umm al-Mu’minin Sayyida Aisha (may Allah be pleased with her) says: The most beloved deed to the Messenger of Allah (peace and blessings be upon him) was that which a person performed consistently.

Abu Salih reports that Umm al-Mu'minin Sayyida Aisha Siddiqa (may Allah be pleased with her) and Sayyida Umm Salama (may Allah be pleased with her) were asked: "Which deed was most beloved to the Messenger of Allah (peace and blessings be upon him)?" They replied: "That which is done consistently, even if it is little."

Asim bin Humaid reports that I heard Sayyiduna Awf bin Malik (may Allah be pleased with him) say: I spent one night with the Messenger of Allah (peace and blessings be upon him). He used the miswak, performed ablution, and then stood up to pray. I also stood up with him. At the beginning, he recited Surah al-Baqarah. Whenever he passed by a verse of mercy, he would pause and ask Allah for it, and whenever he passed by a verse of punishment, he would pause and seek Allah’s protection from it. Then the Messenger of Allah (peace and blessings be upon him) bowed in ruku‘, and remained in ruku‘ for as long as he had stood, and in ruku‘ he would recite this supplication: «سبحان ذي الجبروت والملكوت والكبرياء والعظمة» ,“Glory be to Allah, the Possessor of Might, Dominion, Majesty, and Greatness.”Then he would prostrate for as long as he had bowed, and in prostration he would recite the same supplication: «سبحان ذي الجبروت والملكوت والكبرياء والعظمة» . Then in the (second rak‘ah) the Messenger of Allah (peace and blessings be upon him) recited Surah Aal ‘Imran, then recited one surah after another, and did the same as he had done in the first rak‘ah.
