we have revealed the quran with the truth and with the truth it has come down. we have sent you forth only to give good news and to give warning we have revealed the quran bit by bit so that you may recite it to the people slowly and with deliberation. we have imparted it by gradual revelation.
وبالحق أنزلناه وبالحق نزل وما أرسلناك إلا مبشرا ونذيرا وقرآنا فرقناه لتقرأه على الناس على مكث ونزلناه تنزيلا
