عَنْ أَنَسِ بْنِ مَالِكَ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ عَادَ رَجُلًا مِنَ الْأَنْصَارِ (وَفِي رِوَايَةٍ مِنْ بَنِي النَّجَّارِ) فَقَالَ: ((يَا خَالُ! قُلْ لَا إِلَهَ إِلَّا اللَّهُ))، فَقَالَ: أَخَالٌ أَمْ عَمٌّ؟ فَقَالَ: ((لَا بَلْ خَالٌ))، قَالَ: فَخَيْرٌ لِي أَنْ أَقُولَ لَا إِلَهَ إِلَّا اللَّهُ؟ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَصَحْبِهِ وَسَلَّمَ: ((نَعَمْ))
It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, went to visit a man from the Ansar or Banu Najjar. The Prophet, peace and blessings be upon him, said to him: "Uncle! Say LĀ ILĀHA ILLALLĀH." He said: "Maternal uncle or paternal uncle?" The Prophet, peace and blessings be upon him, replied: "Not paternal uncle, but maternal uncle." He asked: "Is reciting LĀ ILĀHA ILLALLĀH better for me?" The Prophet, peace and blessings be upon him, said: "Yes."
