Surah Saba 34:50

قُلْ إِن ضَلَلْتُ فَإِنَّمَآ أَضِلُّ عَلَىٰ نَفْسِى ۖ وَإِنِ ٱهْتَدَيْتُ فَبِمَا يُوحِىٓ إِلَىَّ رَبِّىٓ ۚ إِنَّهُۥ سَمِيعٌ قَرِيبٌ

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."

Translation: Saheeh International

Tafsir

Say ‘If I go astray from the truth I will be going astray only to my own loss that is to say the sin of my going astray shall be held against me; and if I am rightly guided it will have been by what my Lord reveals to me of the Qur’ān and wisdom. Truly He is Hearer of supplications Nigh’.
