very first of His Almighty's manifestations and the very beginning of creations—to believe in the religion of these Nawasib?

He Almighty said in Surat al-Tawbah:

{And [there are] those [hypocrites] who took for themselves a mosque for causing harm, disbelief, and division among the believers... (up to His saying) ... Never stand [to pray] in it. A mosque founded on righteousness from the first day is more worthy for you to stand in.} (Al-Tawbah: 107-108).

And He Almighty said, addressing His Prophet in Surat Yunus:

{And if they deny you, then say, "For me is my deed, and for you are your deeds. You are disassociated from what I do, and I am disassociated from what you do."} (Yunus: 41).

Similar to it is His Almighty's saying in Surat al-Tawbah:

{Say, "Spend willingly or unwillingly; never will it be accepted from you. Indeed, you have been a defiantly disobedient people." And what prevents their expenditures from being accepted from them except that they have disbelieved in God and in His Messenger and that they come not to prayer except while they are lazy and that they do not spend except while they are unwilling.

So let not their wealth or their children impress you. God only intends to punish them through them in worldly life and that their souls should depart while they are disbelievers.} (Al-Tawbah: 53-55).
