Al-Baqarah 2:186

وَإِذَا سَأَلَكَ عِبَادِي عَنِّي فَإِنِّي قَرِيبٌۖ أُجِيبُ دَعۡوَةَ ٱلدَّاعِ إِذَا دَعَانِۖ فَلۡيَسۡتَجِيبُواْ لِي وَلۡيُؤۡمِنُواْ بِي لَعَلَّهُمۡ يَرۡشُدُونَ 186

And when My servants ask you, [O Muhammad], 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
