Sunan al-Nasa'i — The Book of Purification

“The Messenger of Allah (ﷺ) said: ‘Whoever performs Wudu’ and does it well, then says: “Ashhadu an la ilaha ill-Allah was ashhadu anna Muhammadan ‘abduhu wa rasuluh (I bear witness that there is none worthy of worship except Allah, and I bear witness that Muhammad is his slave and Messenger),” eight gates of Paradise will be opened for him, and he may enter through whichever one he wishes.'”

“Humaid bin Abdur-Rahman bin ‘Awf told me that a man from among the companions of the Prophet (ﷺ) said: ‘I said, when I was on a journey with the Messenger of Allah (ﷺ): By Allah (SWT), I am going to watch the prayer of the Messenger of Allah (ﷺ) and see what he does. When he prayed ‘Isha, he lay down for a long time. Then he woke up and looked toward the horizon and said: “Our Lord! You have not created (all) this without purpose” until he reached: “for You never break (Your) Promise.” Then the Messenger of Allah (ﷺ) reached across his bed and took a siwak from it, then he poured water from a vessel and cleaned his teeth. Then he stood and prayed until I said: He has prayed for as long as he has slept. Then he lay down until I said: He has slept as long as he prayed. Then he woke up and did the same as he had done the first time and said the same as he had said. The Messenger of Allah (ﷺ) did that three times before Fajr.'”

Ibn ‘Alqamah appointed his father to collect the Zakah of his people – and he quoted the same Hadith.

“We used to fast on ‘Ashura and give Zakatul-Fitr, and when the command to fast in Ramadan was revealed, and the command to give Zakah was revealed, we were neither commanded to give it, nor told not to do so, and we used to do it.”

“I lost a camel of mine, so I went to look for it in Arafat on the day of Arafat. I saw the Prophet standing there and said: ‘what is he doing here?’ He is one of the Hums.'”

“The ring of the Prophet was of silver, and its stone (Fass) was made of silver too.”
