Surah Al-Baqarah, Verse 186

وَإِذَا سَأَلَكَ عِبَادِي عَنِّي فَإِنِّي قَرِيبٌۖ أُجِيبُ دَعۡوَةَ ٱلدَّاعِ إِذَا دَعَانِۖ فَلۡيَسۡتَجِيبُواْ لِي وَلۡيُؤۡمِنُواْ بِي لَعَلَّهُمۡ يَرۡشُدُونَ١٨٦

wa-idhā sa-alaka ʿibādī ʿannī fa-innī qarībun ujību daʿwata l-dāʿi idhā daʿāni falyastajībū lī walyu'minū bī laʿallahum yarshudūna

And when My servants ask you, [O Muḥammad], concerning Me - indeed I am near. I respond to the invocation of the supplicant when he calls upon Me. So let them respond to Me [by obedience] and believe in Me that they may be [rightly] guided.
