Al-Arba’īn an-Nawawīyah Ḥadīth [21]

عَنْ أَبِي عَمْرٍو وَقِيلَ: أَبِي عَمْرَةَ سُفْيَانَ بْنِ عَبْدِ اللَّهِ رَضِيَ اللهُ عَنْهُ قَالَ: قُلْتُ: يَا رَسُولَ اللَّهِ، قُلْ لِي فِي الْإِسْلَامِ قَوْلًا لَا أَسْأَلُ عَنْهُ أَحَدًا غَيْرَكَ، قَالَ: قُلْ: آمَنْتُ بِاللّٰهِ، ثُمَّ اسْتَقِمْ. رَوَاهُ مُسْلِمٌ

21 – It is reported on the authority of Abī ‘Amr and he is also called Abī ‘Amrah Sufyān bin ‘Abdillāh (may Allāh be pleased with him) who said:

I said: ‘O Messenger of Allāh, tell me something about Islām which I can ask of no one but you.’ He said: “Say: ‘I believe in Allāh’, and then be steadfast on it.” [Reported by Muslim]
