Quran The True Revelation of Creator

As for Surah Al-Kawthar (Surah 108), there are various reports and traditions regarding its revelation. One common narration is that it was revealed in response to the grief and sorrow felt by Prophet Muhammad (peace be upon him) due to the death of his sons. The revelation served as a consolation and a reminder of the abundant blessings bestowed upon him by Allah, particularly the gift of Al-Kawthar, which is a river in paradise.

Surah AL-Ikhlaas (The Sincerity) revealed in the earliest period at Makkah, when detailed verses of the Quran dealing with the essence and attributes of Allah Almighty had not yet been revealed, and the people hearing, the Holy Prophet's invitation to Allah, wanted to know what was his Lord like to whose worship and service he was calling them.
