(حديث مرفوع) حَدَّثَنَا
أَبُو مُعَاوِيَةَ ، حَدَّثَنَا
الْحَجَّاجُ ، عَنْ
أَبِي إِسْحَاقَ ، عَنْ
عَاصِمِ بْنِ ضَمْرَةَ ، عَنْ
عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ ، قَالَ : سُئِلَ عَنِ الْوَتْرِ ، أَوَاجِبٌ هُوَ ؟ قَالَ : " أَمَّا كَالْفَرِيضَةِ فَلَا ، وَلَكِنَّهَا سُنَّةٌ صَنَعَهَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَصْحَابُهُ حَتَّى مَضَوْا عَلَى ذَلِكَ " .
Someone asked Sayyiduna Ali (may Allah be pleased with him) about Witr, whether it is obligatory. He replied that Witr does not have definitive proof from the Noble Qur'an like the obligatory prayers, but its obligation is established from the Sunnah of the Prophet (peace and blessings be upon him) and his companions (may Allah be pleased with them), and they always performed it.
