وَعَن أبي ذرٍ أَنَّهُ قَالَ وَهُوَ آخِذٌ بِبَابِ الْكَعْبَةِ: سَمِعْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «أَلَا إِنَّ مِثْلَ أَهْلِ بَيْتِي فِيكُمْ مِثْلُ سَفِينَةِ نُوحٍ مَنْ رَكِبَهَا نَجَا وَمَنْ تَخَلَّفَ عَنْهَا هلك» . رَوَاهُ أَحْمد

Abu Dharr, while holding the door of the Ka’ba, told that he had heard the Prophet say, “My family among you are like Noah’s ark. He who sails on it[*] will be safe, but he who- holds back from it will perish.” *A figure of speech for showing love to the Prophet’s family. Ahmad transmitted it.
