السلام عليكم ورحمة الله وبركاته Ustadh hayakallah, shaykh salih al ash shaykh mentiones in his sharh thalathatul usool, when he explains shar3i imān, that this imān is where the ibtlia‘ happened. What is the إبتلاء that happened? And which people were those in ibtila‘? BarakaAllahu feekum

Ustadh AbdulAziz al-Haqqan
Many groups deviated in regards to it some peopl for example say that actions are not part of Iman which means the Iman of the Prophets is like the Iman of sinners and there are many wrong sets of beliefs regarding it.
