It is narrated from Hazrat Abu Ayyub Ansari (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: Whoever recites these words ten times: "La ilaha illallah wahdahu la sharika lahu, lahul mulk wa lahul hamd, yuhyi wa yumit wa huwa 'ala kulli shay'in qadeer," Allah Almighty will write ten good deeds for him for each time, forgive ten sins, raise him by ten degrees, and it will be as if he has freed ten slaves. And these will become his protection from the beginning to the end of the day, and no one will be able to do a deed that surpasses his on that day. And if he says it in the evening, it will be the same.

It is narrated from Hazrat Abu Ayyub Ansari (may Allah be pleased with him) that on the day of the Battle of Badr, we formed rows, and one man from among us went ahead of the row. The Noble Prophet (peace and blessings be upon him) saw him and said, "Stay with me, stay with me."

It is narrated from Hazrat Abu Ayyub Ansari (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) stayed on the lower floor of our house and I used to live on the upper floor. One day, water spilled in my room, so I and Umm Ayyub took a sheet and started drying the water so that it would not drip from the ceiling onto the Noble Prophet (peace and blessings be upon him). Then, fearfully, I went to the service of the Noble Prophet (peace and blessings be upon him) and submitted, "O Messenger of Allah! It is not appropriate that we stay above you; please move upstairs." So, on the order of the Noble Prophet (peace and blessings be upon him), his belongings—which were already very few—were moved upstairs. Then I submitted, "O Messenger of Allah! The food you used to send me before, I would look at it and wherever I sensed the marks of your fingers, I would place my hand there. But today, in the food you sent me, even after looking, I did not see the marks of your fingers." The Noble Prophet (peace and blessings be upon him) said, "That is correct. Actually, there was onion in it, and I do not like to eat it because of the angel who comes to me. However, you may eat it."

Hazrat Abu Abdur Rahman says that I asked my father, Imam Ahmad (may Allah have mercy on him), that someone says whoever performs two rak'ahs in the mosque after Maghrib, it is not permissible unless he performs them at home, because the Noble Prophet (peace and blessings be upon him) said: "This is among the prayers of the home." He asked, "Who says this?" I replied, "Muhammad bin Abdur Rahman." He said, "He has spoken well."

It is narrated from Hazrat Abu Ayyub (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever performs ghusl on Friday or attains purity and does it well, wears fine clothes, applies perfume or oil, then comes for Jumu’ah, reaches the mosque and, if there is time, offers prayer, does not engage in idle talk, does not harm anyone, and when the Imam comes out, remains silent, then his sins will be expiated until the next Friday.

It is narrated from Hazrat Abu Ayyub Ansari (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) performed the Maghrib and Isha prayers together at the plain of Muzdalifah.

Ali bin Mudrik says that once I saw Hazrat Abu Ayyub (may Allah be pleased with him) taking off his leather socks during ablution. People began to look at him with surprise, so he said, "It is certain that I saw the Prophet Muhammad (peace and blessings be upon him) wiping over his leather socks, but I prefer to wash my feet."

It is narrated from Hazrat Abu Ayyub Ansari (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: The obligation of ghusl (ritual bath) is due to the emission of semen.

It is narrated from Hazrat Abu Ayyub Ansari (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: It is not lawful for a Muslim to sever relations with his brother for more than three days; when they meet, one turns his face this way and the other that way, and the better of the two is the one who greets first.

It is narrated from Hazrat Abu Ayyub Ansari (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: When any one of you goes to the toilet, he should not face the Qiblah, rather he should turn towards the east or the west. But when we reached Syria, we found that the toilets there were built facing the Qiblah, so we would turn our faces away in them and seek forgiveness.
