Hadith 4478

(حديث مرفوع) حَدَّثَنَا إِسْمَاعِيلُ ، حَدَّثَنَا أَيُّوبُ ، عَنْ نَافِعٍ ، قَالَ : نَادَى ابْنُ عُمَرَ بِالصَّلَاةِ بِضَجْنَانَ ، ثُمَّ نَادَى أَنْ صَلُّوا فِي رِحَالِكُمْ ، ثُمَّ حَدَّثَ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : أَنَّهُ كَانَ يَأْمُرُ الْمُنَادِيَ ، فَيُنَادِي بِالصَّلَاةِ ثُمَّ يُنَادِي ، أَنْ " صَلُّوا فِي رِحَالِكُمْ ، فِي اللَّيْلَةِ الْبَارِدَةِ ، وَفِي اللَّيْلَةِ الْمَطِيرَةِ ، فِي السَّفَرِ " .
Nafi' reports that once in the valley of Dajnan, Sayyiduna Ibn Umar (may Allah be pleased with them both) had the call for prayer announced, then made this proclamation: "Pray in your tents." And he narrated this hadith from the Prophet Muhammad (peace and blessings be upon him) that the Prophet (peace and blessings be upon him), while traveling on cold nights or rainy nights, would have the call for prayer announced and then proclaim: "Pray in your tents."
