Surah Saba, ayah 50

قُلۡ إِن ضَلَلۡتُ فَإِنَّمَآ أَضِلُّ عَلَىٰ نَفۡسِيۖ وَإِنِ ٱهۡتَدَيۡتُ فَبِمَا يُوحِيٓ إِلَيَّ رَبِّيٓۚ إِنَّهُۥ سَمِيعٞ قَرِيبٞ ٥٠

Qul in dalaltu fa innamā adillu 'alā nafsī wa inihtadaytu fabimā yūhī ilayya rabbī innahū samī'un qarīb

Say, "If I should err, I would only err against myself. But if I am guided, it is by what my Lord reveals to me. Indeed, He is Hearing and near."
