عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: سَمِعْتُ عُمَرَ بْنَ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ يَقُولُ لِطَلْحَةَ بْنِ عُبَيْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُ: مَا لِي أَرَاكَ شَعِثًا وَأَغْبَرَّتَ مُنْذُ تُوُفِّيَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ، لَعَلَّكَ سَاءَكَ يَا طَلْحَةُ! إِمَّارَةُ ابْنِ عَمِّكَ؟ قَالَ: مَعَاذَ اللَّهِ، إِنِّي لَأَجْدَرُكُمْ أَنْ لَا أَفْعَلَ ذَلِكَ، إِنِّي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ: ((إِنِّي لَأَعْلَمُ كَلِمَةً لَا يَقُولُهَا أَحَدٌ عِنْدَ حَضْرَةِ الْمَوْتِ إِلَّا وَجَدَ رُوحُهُ لَهَا رَوْحًا، حِينَ يَخْرُجُ مِنْ جَسَدِهِ، وَكَانَتْ لَهُ نُورًا يَوْمَ الْقِيَامَةِ))، فَلَمْ أَسْأَلْ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ، وَلَمْ يُخْبِرْنِي بِهَا، فَذَاكَ الَّذِي دَخَلَنِي، قَالَ عُمَرُ رَضِيَ اللَّهُ عَنْهُ: فَأَنَا أُعْلِمُهَا، قَالَ: فَلِلَّهِ الْحَمْدُ فَمَا هِيَ؟ قَالَ: هِيَ الْكَلِمَةُ الَّتِي قَالَهَا لِعَمِّهِ (لَا إِلَهَ إِلَّا اللَّهُ)، قَالَ طَلْحَةُ: صَدَقْتَ
Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) says: I heard that Sayyiduna Umar bin Khattab (may Allah be pleased with him) was asking Sayyiduna Talhah bin Ubaidullah (may Allah be pleased with him): What is the matter that since the day the Messenger of Allah (peace and blessings be upon him) passed away, you have remained disheveled and covered in dust? Is it that you disliked your cousin (Abu Bakr Siddiq, may Allah be pleased with him) becoming the leader? Sayyiduna Talhah (may Allah be pleased with him) said: Allah's refuge! I am even more deserving than you not to do such a thing, (why would I dislike this matter). The fact is that I heard the Messenger of Allah (peace and blessings be upon him) saying: I know a word, whoever recites it at the time of death, as soon as his soul leaves his body, he attains mercy and comfort, and that word will be a source of light for him on the Day of Resurrection. But alas, I could neither ask you (peace and blessings be upon him) about that word nor did you (peace and blessings be upon him) explain it to me. This has made me sorrowful. Sayyiduna Umar (may Allah be pleased with him) said: I know that word. Upon hearing this, Sayyiduna Talhah (may Allah be pleased with him) said: Praise be to Allah, what is that word? He (may Allah be pleased with him) said: It is the word which the Messenger of Allah (peace and blessings be upon him) presented to his uncle (Abu Talib), that is, LAA ILAAHA ILLALLAH (There is no god but Allah). He said: You have spoken the truth.
