عَنْ هِشَامِ بْنِ عُرْوَةَ قَالَ أَخْبَرَنِي أَبِي عَنْ عَبْدِ اللَّهِ بْنِ أَرْقَمَ رَضِيَ اللَّهُ عَنْهُ أَنَّهُ حَجَّ فَكَانَ يُصَلِّي بِأَصْحَابِهِ يُؤَذِّنُ وَيُقِيمُ، فَأَقَامَ يَوْمًا الصَّلَاةَ وَقَالَ: لِيُصَلِّ أَحَدُكُمْ، فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ: ((إِذَا أَرَادَ أَحَدُكُمْ أَنْ يَذْهَبَ إِلَى الْخَلَاءِ وَأُقِيمَتِ الصَّلَاةُ فَلْيَذْهَبْ إِلَى الْخَلَاءِ))
Urwah reports that Sayyiduna Abdullah bin Arqam (may Allah be pleased with him) performed Hajj. During this journey, he would give the call to prayer (adhan) and lead his companions in prayer. One day, he stood up to lead the prayer, but then said: "Let one of you lead the prayer, for I heard the Messenger of Allah (peace and blessings be upon him) say: When any of you intends to relieve himself and the prayer has been established, he should relieve himself first."
