What is the best time to say "None has the right to be worshipped but Allah alone, He has no partner. To Him belongs all sovereignty and praise. He grants life and causes death, and He has power over all things" ten times? And does this number have a benefit? And what about the virtue of saying "Allah is Most Great, Most Great, and praise be to Allah abundantly, morning and evening" and other supplications?

It is narrated regarding the virtue of saying "There is no god but Allah alone, He has no partner. To Him belongs all sovereignty and all praise. He gives life and causes death, and He is over all things competent" ten times after the Fajr and Maghrib prayers. There is a greater reward for whoever says it one hundred times in the morning and evening. The best time to say it is immediately after the Fajr and Maghrib prayers. The reward for one who says it ten times does not contradict the reward for one who adds to that, and there is no objection to exceeding one hundred times. Rather, the one who says it may have additional virtue commensurate with their increase.
