Rifa`a Al-Qurazi divorced his wife irrevocably (i.e. that divorce was the final). Later on `Abdur-
Rahman bin Az-Zubair married her after him. She came to the Prophet (ﷺ) and said, "O Allah's Messenger (ﷺ)! I
was Rifa`a's wife and he divorced me thrice, and then I was married to `Abdur-Rahman bin AzZubair,
who, by Allah has nothing with him except something like this fringe, O Allah's Messenger (ﷺ)," showing a
fringe she had taken from her covering sheet. Abu Bakr was sitting with the Prophet (ﷺ) while Khalid Ibn
Sa`id bin Al-As was sitting at the gate of the room waiting for admission. Khalid started calling Abu
Bakr, "O Abu Bakr! Why don't you reprove this lady from what she is openly saying before Allah's
Apostle?" Allah's Messenger (ﷺ) did nothing except smiling, and then said (to the lady), "Perhaps you want
to go back to Rifa`a? No, (it is not possible), unless and until you enjoy the sexual relation with him
(`Abdur Rahman), and he enjoys the sexual relation with you."
Sahih al-Bukhari Book 78, Hadith 112
Aishah told him that the Messenger of Allah (ﷺ) used to say the following supplication in his prayer: Allahumma inni audhu bika min 'adhab ilqabri wa 'audhu bika min fitnatil-masihid-dajjal, wa 'audhu bika min fitnatil-mahya walmamati, Allahumma inni 'audhu bika min al-ma'thami wal-maghram ( O Allah, I seek refuge with You from the torment of the grave, and I seek refuge in You from the tribulation of the Al-Masihid-Dajjal, and I seek refuge with You from the trials of life and death. O Allah, I seek refuge in You from sin and debt.) Someone said to him: "How often you seek refuge from debt!" He said: "If a man gets into debt, when he speaks lies, and when he makes a promise, he betrays it."
