We want your excellency to encourage the callers [to Islaam] and the students of knowledge to establish lessons and lectures in all of the regions of [all] the countries…
During the Messenger’s (sal-Allaahu ‘alayhi wa sallam) time, did Islaam reach Europe? If it did, then how did it reach them, and how did they react?
How should the Muslim engage in inviting [da’wah] to Islaam? And what is the best way to undertake da’wah [activities]?
What does the [following] saying of the Messenger (sal-Allaahu ‘alayhi wa sallam) mean: «اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عِلْمٍ لاَ يَنْفَعُ»?
If a caller [to Islaam] invites [someone] to [do] something which he is unable to do himself – even after having tried – but finds the one he is inviting will be able to do it, should he [still] invite him to do it?
