Hadith 396
نا سَلْمُ بْنُ جُنَادَةَ ، نا وَكِيعٌ ، عَنْ سُفْيَانَ ، عَنْ خَالِدٍ الْحَذَّاءِ ، عَنْ أَبِي قِلابَةَ ، عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ ، قَالَ : أَتَيْنَا رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَا وَابْنُ عَمٍّ لِي ، فَقَالَ : " إِذَا سَافَرْتُمَا ، فَأَذِّنَا وَأَقِيمَا وَلْيَؤُمَّكُمَا أَكْبَرُكُمَا "
Sayyiduna Malik bin Huwairith (may Allah be pleased with him) narrates that my cousin and I presented ourselves in the noble service of the Messenger of Allah (peace and blessings be upon him). So (at the time of farewell) the Prophet (peace and blessings be upon him) said: "When both of you travel, give the adhan and say the takbir, and let the elder of you lead the prayer."
