Question:
What do you say about the work of Da`wah and Tabligh?
Answer:
In the Name of Allah, Most Merciful and Compassionate.
Calling people to true religion and belief in their Creator is a communal obligation, and whoever is striving to fulfill it has tremendous reward, even if they may have some shortcomings at the personal or collective level.
And Allah alone gives success.
