Arabic (Original)
حَدَّثَنَا أَبُو كَامِلٍ حَدَّثَنَا إِبْرَاهِيمُ يَعْنِي ابْنَ سَعْدٍ حَدَّثَنَا ابْنُ شِهَابٍ وَيَزِيدُ بْنُ هَارُونَ قَالَ أَنْبَأَنَا إِبْرَاهِيمُ قَالَ حَدَّثَنِي ابْنُ شِهَابٍ عَنْ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ مَاعِزٍ الْعَامِرِيِّ عَنْ سُفْيَانَ بْنِ عَبْدِ اللَّهِ الثَّقَفِيِّ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ حَدِّثْنِي بِأَمْرٍ أَعْتَصِمُ بِهِ قَالَ قُلْ رَبِّيَ اللَّهُ ثُمَّ اسْتَقِمْ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ مَا أَكْبَرُ مَا تَخَافُ عَلَيَّ قَالَ فَأَخَذَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِلِسَانِ نَفْسِهِ ثُمَّ قَالَ هَذَا قَالَ يَزِيدُ فِي حَدِيثِهِ بِطَرْفِ لِسَانِ نَفْسِهِ.
English Translation
Abu Kamil told us: Ibrahim - meaning Ibn Sa'd - told us: Ibn Shihab told us; and Yazid ibn Harun said: Ibrahim informed us: Ibn Shihab told me, from Muhammad ibn Abd al-Rahman ibn Ma'iz al-Amiri, from Sufyan ibn Abdullah al-Thaqafi, who said: I said, "O Messenger of Allah, tell me something I can hold fast to." He said: "Say: My Lord is Allah, then remain steadfast." I said: "O Messenger of Allah, what is the greatest thing you fear for me?" He said: The Messenger of Allah, peace and blessings be upon him, took hold of his own tongue, then said: "This." Yazid said in his hadith: "by the tip of his own tongue."
