I went to Quba' with the Messenger of Allah ﷺ on Monday till we reached (the habitation) of Banu Salim. The Messenger of Allah ﷺ stood at the door of 'Itban and called him loudly. So he came out dragging his lower garnment. Upon this the Messenger of Allah ﷺ said: We have made this man to make haste 'Itban said: Messenger of Allah, if a man parts with his wife suddenly without seminal emission, what is he required to do (with regard to bath)? The Messenger of Allah ﷺ said: It is with the seminal emission that bath becomes obligatory.
خَرَجْتُ مَعَ رَسُولِ اللَّهِ ﷺ يَوْمَ الاِثْنَيْنِ إِلَى قُبَاءٍ حَتَّى إِذَا كُنَّا فِي بَنِي سَالِمٍ وَقَفَ رَسُولُ اللَّهِ ﷺ عَلَى بَابِ عِتْبَانَ فَصَرَخَ بِهِ فَخَرَجَ يَجُرُّ إِزَارَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ أَعْجَلْنَا الرَّجُلَ فَقَالَ عِتْبَانُ يَا رَسُولَ اللَّهِ أَرَأَيْتَ الرَّجُلَ يُعْجَلُ عَنِ امْرَأَتِهِ وَلَمْ يُمْنِ مَاذَا عَلَيْهِ قَالَ رَسُولُ اللَّهِ ﷺ إِنَّمَا الْمَاءُ مِنَ الْمَاءِ
