A du3ā the Prophet صلى الله عليه وسلم did on 3Uthmān رضي الله عنه

16 – 361 وروينا فيه عن عثمان بن عفان رضي الله عنه قال: مرضت فكان رسول الله صلى الله عليه وسلم يعوّذني فعّوذني يوماً فقال: «بِسْمِ الله الرَّحْمَنِ الرَّحِيمِ أُعِيذُكَ بالله الأَحَدِ الصَّمَدِ الَّذِي لمْ يَلِدْ وَلمْ يُولَدْ ولمْ يَكُنْ لَهُ كُفُواً أحَدٌ مِنْ شَرّ ما تَجِدُ». فلما استقلَّ رسول الله صلى الله عليه وسلم قائماً قال: «يا عُثْمَانُ تَعَوَّذْ بِها فَمَا تَعَوَّذْتُمْ بِمِثْلِها».

‘Aa-isha: I scraped it off with my nails

(32) Chapter: The ruling on sperm

Abdullāh bin Shihāb al-Khaulani reported:

I stayed in the house of ‘Aa-isha and had a wet dream (and perceived its effect on my garment), so (in the morning) I dipped both (the clothes) in water. This (act of mine) was watched by a maid-servant of ‘Aa-isha and she informed her. She (Hadrat ‘Aa-isha) sent me a message: What prompted you to act like this with your clothes? He (the narrator) said: I told that I saw in a dream what a sleeper sees. She said: Did you find (any mark of the fluid) on your clothes? I said: No. She said: Had you found anything you should have washed it. In case I found that (semen) on the garment of the Messenger of Allah (ﷺ) dried up, I scraped it off with my nails.

Narrated Anas:

A funeral procession passed in front of the Prophet (ﷺ) and the people praised the deceased. The Prophet (ﷺ) said, “It has been affirmed (Paradise).” Then another funeral procession passed by and the people talked badly of the deceased. The Prophet (ﷺ) said, “It has been affirmed (Hell).” Allah’s Messenger (ﷺ) was asked, “O Allah’s Messenger (ﷺ)! You said it has been affirmed for both?” The Prophet (ﷺ) said, “The testimony of the people (is accepted), (for) the believer are Allah’s witnesses on the earth.”

حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ مُرَّ عَلَى النَّبِيِّ صلى الله عليه وسلم بِجَنَازَةٍ، فَأَثْنَوْا عَلَيْهَا خَيْرًا فَقَالَ ‏”‏ وَجَبَتْ ‏”‏‏.‏ ثُمَّ مُرَّ بِأُخْرَى فَأَثْنَوْا عَلَيْهَا شَرًّا ـ أَوْ قَالَ غَيْرَ ذَلِكَ ـ فَقَالَ ‏”‏ وَجَبَتْ ‏”‏‏.‏ فَقِيلَ يَا رَسُولَ اللَّهِ، قُلْتَ لِهَذَا وَجَبَتْ، وَلِهَذَا وَجَبَتْ، قَالَ ‏”‏ شَهَادَةُ الْقَوْمِ، الْمُؤْمِنُونَ شُهَدَاءُ اللَّهِ فِي الأَرْضِ ‏”‏‏.‏
