Assalam 'Alaykum Ustadh, I have 2 questions: (1) Is there authentic evidence on the exact number of prophets and messengers? I saw a narration of 124,000 prophets and 315 messengers. (2) Can I benefit from Sheikh Muhammad Al Jibaly’s 6 books titled Iman Made Easy?

Ustadh AbdulAziz al-Haqqan
Some of the people of ilm authenticated the hadeeth, yes. As for the book I do not know.
