Hadith 6140
Zaid b. Arqam told that God's messenger got up among them one day at a watering-place called Khumm between Mecca and Medina to address them. He praised and extolled God, gave a warning and a reminder, and then said, "To proceed: You people must understand that I am just human. My Lord's messenger will soon come for me and I shall answer his summons, but I am leaving among you the two important things, the first of which is God's Book which contains guidance and light, so study it and follow its commands closely." Then when he had urged attention to God's Book and commended it, he said, "Also my family. I remind you of your duty to God to care for my family; I remind you of your duty to God to care for my family." A version has "God's Book is God's rope; he who follows it has guidance and he who abandons it is in error." Muslim transmitted it.
وَعَنْ زَيْدِ بْنِ أَرْقَمَ قَالَ: قَامَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَوْمًا فِينَا خَطِيبًا بِمَاءٍ يُدْعَى: خُمًّا بَيْنَ مَكَّةَ وَالْمَدِينَةِ فَحَمِدَ اللَّهَ وَأَثْنَى عَلَيْهِ وَوَعَظَ وَذَكَّرَ ثُمَّ قَالَ: " أمَّا بعدُ أَلا أيُّها النَّاس فَإِنَّمَا أَنَا بَشَرٌ يُوشِكُ أَنْ يَأْتِيَنِي رَسُولُ رَبِّي فَأُجِيبَ وَأَنَا تَارِكٌ فِيكُمُ الثَّقَلَيْنِ: أَوَّلُهُمَا كِتَابُ اللَّهِ فِيهِ الْهُدَى وَالنُّورُ فَخُذُوا بِكِتَابِ اللَّهِ وَاسْتَمْسِكُوا بِهِ " فَحَثَّ عَلَى كِتَابِ اللَّهِ وَرَغَّبَ فِيهِ ثُمَّ قَالَ: «وَأَهْلُ بَيْتِي أُذَكِّرُكُمُ اللَّهَ فِي أَهْلِ بَيْتِي أُذَكِّرُكُمُ اللَّهَ فِي أَهْلِ بَيْتِي» وَفِي رِوَايَة: «كتاب الله عز وَجل هُوَ حَبْلُ اللَّهِ مَنِ اتَّبَعَهُ كَانَ عَلَى الْهُدَى وَمَنْ تَرَكَهُ كَانَ عَلَى الضَّلَالَةِ» . رَوَاهُ مُسلم
