Arabic (Original)
قَالَ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ عَنْ هِشَامٍ قَالَ حَدَّثَنِي أَبِي عَنْ عَبْدِ اللَّهِ بْنِ أَرْقَمَ أَنَّهُ خَرَجَ مِنْ مَكَّةَ وَكَانَ يَؤُمُّهُمْ وَيُؤَذِّنُ وَيُقِيمُ فَأَقَامَ يَوْمًا الصَّلَاةَ فَقَالَ لِيُصَلِّ بِكُمْ رَجُلٌ مِنْكُمْ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ إِذَا أَرَادَ أَحَدُكُمْ أَنْ يَذْهَبَ إِلَى الْخَلَاءِ وَأُقِيمَتْ الصَّلَاةُ فَلْيَذْهَبْ إِلَى الْخَلَاءِ.
English Translation
He said: Yahya ibn Sa'id told us, from Hisham, who said: my father told me, from Abdullah ibn Arqam, that he went out from Mecca and used to lead them in prayer and give the call and the iqama. One day he began the prayer, then said: "Let a man among you lead the prayer, for I heard the Messenger of Allah, peace and blessings be upon him, say: 'When one of you wants to go to relieve himself and the prayer has been started, let him go to relieve himself.'"
