وَإِذَا سَأَلَكَ عِبَادِى عَنِّى فَإِنِّى قَرِيبٌ ۖ أُجِيبُ دَعْوَةَ ٱلدَّاعِ إِذَا دَعَانِ ۖ فَلْيَسْتَجِيبُوا۟ لِى وَلْيُؤْمِنُوا۟ بِى لَعَلَّهُمْ يَرْشُدُونَ
And when My servants question thee concerning Me, then surely I am nigh. I answer the prayer of the suppliant when he crieth unto Me. So let them hear My call and let them trust in Me, in order that they may be led aright.
