Shaykh Yasir discusses the Du'a of Prophet Musa.
'O Allah! Make my heart at ease..'[Surah Taha -Verses 25-35]
The first act of worship that Musa [AS] does is dua directly addressing Allah SWT. We can derive important things from this Dua:
To make his heart tranquil and at ease.To make this affair easy for him.To solve his problem of stuttering.To give him a helper from his own family.To make his helper a Prophet along with him being a Prophet too.
