Arabic (Original)
حَدَّثَنَا عَلِيُّ بْنُ إِسْحَاقَ قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ يَعْنِي ابْنَ الْمُبَارَكِ قَالَ أَنْبَأَنَا مَعْمَرٌ عَنِ الزُّهْرِيِّ عَنْ عَبْدِ الرَّحْمَنِ بْنِ مَاعِزٍ 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 أَخْوَفُ مَا تَخَافُ عَلَيَّ قَالَ فَأَخَذَ بِلِسَانِ نَفْسِهِ ثُمَّ قَالَ هَذَا.
English Translation
Ali ibn Ishaq told us: Abdullah - meaning Ibn al-Mubarak - informed us: Ma'mar informed us, from al-Zuhri, from Abd al-Rahman ibn Ma'iz, 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 most fearsome thing you fear for me?" He took hold of his own tongue, then said: "This."
