“Call upon Allah while being certain of being answered, and know that Allah does not respond to a supplication from the heart of one heedless and occupied by play.” (Using translation from Tirmidhī 3479)
عَنِ النَّبِيِّ ﷺ قَالَ «ادْعُوا اللَّهَ وَأَنْتُمْ مُوقِنُونَ بِالْإِجَابَةِ وَاعْلَمُوا أَنَّ اللَّهَ لَا يَقْبَلُ دُعَاءً مِنْ قَلْبٍ غَافِلٍ لَاهٍ»
