Fatwā from Shaykh Sāliḥ al-Fawzān:

Question: Is it correct that the duʿā (supplication) and al-Istighfār (seeking Allah’s forgiveness) between the adhān and the iqāmah is better than the recitation of the Qur’ān (during this time)?

Answer: Yes. That’s because the duʿā between the adhān and the iqāmah is something that is sure (to be an act of worship done at this specific time). It is legislated. The duʿā between the adhān and the iqāmah is not rejected and (if it is not done at this time), its (benefit) can be missed. As for the recitation of the Qur’ān, (the benefit of) it can not be missed because its time (of reciting it) is vast and it can be recited at another time.
