My Lord is Allah

عَنْ سُفْيَانَ بْنِ عَبْدِ اللہِ الثَّقَفِیِّ، قَالَ قُلْتُ يَا رَسُوْلَ اللہِ حَدِّثْنِیْ بِأَمْرٍ أَعْتَصِمُ بِهِ قَالَ قُلْ رَبِّیَ اللہُ ثُمَّ اسْتَقِمْ قُلْتُ يَا رَسُوْلَ اللہِ مَا أَخْوَفُ مَا تَخَافُ عَلَىَّ فَأَخَذَ بِلِسَانِ نَفْسِهِ ثُمَّ قَالَ‏ هَذَا

Hazrat Sufyan^ra bin Abdullah al-Thaqafi narrates:

“I said: ‘O Messenger of Allah! Inform me about a matter that I may hold fast to.’ He said: ‘Say: “My Lord is Allah”, then be steadfast.’ I said: ‘O Messenger of Allah! What do you fear most for me?’ So he took hold of his tongue and said: ‘This.’”
