عَنْ سَعِيدِ بْنِ الْحَارِثِ قَالَ: دَخَلْنَا عَلَى جَابِرِ بْنِ عَبْدِ اللَّهِ وَهُوَ يُصَلِّي فِي ثَوْبٍ وَاحِدٍ مُلْتَحِفٌ بِهِ وَرِدَاؤُهُ قَرِيبٌ لَوْ تَنَاوَلَهُ بَلَغَهُ، فَلَمَّا سَلَّمَ سَأَلْنَاهُ عَنْ ذَلِكَ، فَقَالَ: إِنَّمَا أَفْعَلُ هَٰذَا لِيَرَانِيَ الْحَمْقَى أَمْثَالُكُمْ فَيُفْشُوا عَلَى جَابِرٍ رُخْصَةً رَخَّصَهَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ثُمَّ قَالَ جَابِرٌ: خَرَجْتُ مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فِي بَعْضِ أَسْفَارِهِ فَجِئْتُهُ لَيْلَةً وَهُوَ يُصَلِّي فِي ثَوْبٍ وَاحِدٍ، وَعَلَيَّ ثَوْبٌ وَاحِدٌ فَاشْتَمَلْتُ بِهِ، ثُمَّ قُمْتُ إِلَى جَنْبِهِ، قَالَ: ((يَا جَابِرُ! مَا هَٰذَا الِاشْتِمَالُ؟ إِذَا صَلَّيْتَ وَعَلَيْكَ ثَوْبٌ وَاحِدٌ فَإِنْ كَانَ وَاسِعًا فَالْتَحِفْ بِهِ، وَإِنْ كَانَ ضَيِّقًا فَاتَّزِرْ بِهِ))
Saeed bin Harith says: We entered upon Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) while he was wrapped in a single garment and performing prayer, even though his upper sheet was so close to him that if he wanted to grab it, he could have. Anyway, when he finished the prayer with salam, we asked him about this clothing, so he said: I have done this only so that fools like you may see me and spread talk about such a concession for Jabir which the Messenger of Allah (peace and blessings be upon him) had permitted. Then Sayyiduna Jabir (may Allah be pleased with him) said: I went out with the Messenger of Allah (peace and blessings be upon him) on a journey, and when I came to him at night during the journey, he was praying in a single garment, and I too had only one garment, so I wrapped it around myself and stood on his side. The Messenger of Allah (peace and blessings be upon him) said: Jabir! What is this wrapping? When you pray in such a state that you have only one garment, if it is wide, then cover yourself with it, and if the garment is tight, then tie it as an izar (lower garment) only.
