Shaykh Yasir Qadhi discusses the story of the da'wah of Yusuf AS within the confines of prison in Verses 36 to 41 of Surah Yusuf.
Two young lads entered the prison with Yusuf AS who were the bread maker and winemaker in the palace and both were tried with trying to poison the king. They each had a dream. What were the dreams and what were their interpretations? Listen intently to acquaint yourself with these interesting dreams .
Yusuf AS established a good reputation in the prison by being kind, merciful and helpful to the prison mates. The dreams of the lads were shared to Yusuf AS and he was the apt person to interpret their dreams as Allah had blessed him with the knowledge of interpreting dreams. But Yusuf AS stalled the interpretation for hope of bringing the lads closer to Islam. He tells them to wait till their next meal comes.
How did he change the topic from dreams to Allah? Discover the details. Then, he goes off on the tangent of da'wah to come towards Allah.
We are also acquainted with the methodology adopted by Yusuf AS to advocate the Greatness of Allah SWT and Dawah of Islam. He dissociates himself from idolatry and believes in One God and the HereAfter. He also says he believes in the teachings taught by Prophets Ibrahim, Yaqub and Ishaq AS.
