Sunan Ibn Majah, Book 1, Hadith 329 (In-Book) ⓘ
It was narrated that Jabir bin 'Abdullah said: "The Messenger of Allah forbade us to urinate while standing." (Da'if) I heard Muhammed bin Yazid, Abu 'Abdullah, say: "I heard Ahmad bin 'Abdur-Rahman Al-Makhzumi say: 'Sufyan Ath-Thawri said concerning the Hadith of 'Aisha- 'I (always) saw him urinating whilst sitting down' - a man knows more about that (about such matters) than she.' Ahmad bin 'Abdur-Rahman said: 'It was the custom of the Arabs to urinate standing up. Do you not see that in the Hadith of 'Abdur-Rahman bin Hasanah it was said: 'He sits down to urinate as a woman does.'"
حَدَّثَنَا يَحْيَى بْنُ الْفَضْلِ، حَدَّثَنَا أَبُو عَامِرٍ، حَدَّثَنَا عَدِيُّ بْنُ الْفَضْلِ، عَنْ عَلِيِّ بْنِ الْحَكَمِ، عَنْ أَبِي نَضْرَةَ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ نَهَى رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ أَنْ يَبُولَ قَائِمًا . سَمِعْتُ مُحَمَّدَ بْنَ يَزِيدَ أَبَا عَبْدِ اللَّهِ يَقُولُ سَمِعْتُ أَحْمَدَ بْنَ عَبْدِ الرَّحْمَنِ الْمَخْزُومِيَّ يَقُولُ قَالَ سُفْيَانُ الثَّوْرِيُّ - فِي حَدِيثِ عَائِشَةَ أَنَا رَأَيْتُهُ يَبُولُ قَاعِدًا - قَالَ الرَّجُلُ أَعْلَمُ بِهَذَا مِنْهَا . قَالَ أَحْمَدُ بْنُ عَبْدِ الرَّحْمَنِ كَانَ مِنْ شَأْنِ الْعَرَبِ الْبَوْلُ قَائِمًا أَلاَ تَرَاهُ فِي حَدِيثِ عَبْدِ الرَّحْمَنِ ابْنِ حَسَنَةَ يَقُولُ قَعَدَ يَبُولُ كَمَا تَبُولُ الْمَرْأَةُ .
