عَنْ جَابِرِ بْنِ سَمُرَةَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: سَمِعْتُ رَجُلًا سَأَلَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: أُصَلِّي فِي ثَوْبِي الَّذِي آتِي فِيهِ أَهْلِي؟ قَالَ: ((نَعَمْ، إِلَّا أَنْ تَرَى فِيهِ شَيْئًا تَغْسِلُهُ))
It is narrated from Sayyiduna Jabir bin Samurah (may Allah be pleased with him) that a man asked the Noble Prophet (peace and blessings be upon him): "Can I pray in the garment in which I go to my wife?" The Prophet (peace and blessings be upon him) replied: "Yes, but if you see anything (impure) on it, then wash it."
