Hadith 3026
Narrated Uthman ibn Abul As: When the deputation of Thaqif came to the Messenger of Allah ﷺ, he made them stay in the mosque, so that it might soften their hearts. They stipulated to him that they would not be called to participate in Jihad, to pay zakat and to offer prayer. The Messenger of Allah ﷺ said: You may have the concession that you will not be called to participate in jihad and pay zakat, but there is no good in a religion which has no bowing (i. e. prayer).
Hadith 3891
Uthman bin Abl al-As said that he came to the Messenger of Allah ﷺ. Uthman said: I had a pain which was about to destroy me. So the Prophet ﷺ said: Wipe it with your right hand seven times and say: “I seek refuge in the dominance of Allah, and His might from the evil of what I find. ” Then I did it. Allah removed (the pain) that I had, and I kept on suggesting it to my family and to others.
