In the book “selected benefits” Page 81, print: Daarul Imaan:

The definition of Da’wah:

Ash-Shaykh Islaam Ibn Taymiyyah, may Allah have mercy upon him, said:

“It is calling to the belief in Allah, and that which the Messengers came with of that which they have informed of and obeying them in that which they commanded, so calling to it is da’wah to Allah.”
