Yes the best best gift anyone can have is Islaam, because without it a person is doomed for eternity...perhaps you should have asked what is the best gift AFTER Islaam...well of course then comes having Eemaan, parents, being able to learn/recite Qur'aan, all kinds of both Islamic and wordly things.
A beautiful aayah for us to note (meaning in english):
"And He gave you of all that you asked for, and if you count the Blessings of Allâh, never will you be able to count them. Verily, man is indeed an extreme wrong-doer, a disbeliever (an extreme ingrate who denies Allâh’s Blessings by disbelief, and by worshipping others besides Allâh, and by disobeying Allâh and His Prophet Muhammad(saw)." [Ibraheem: 34]
164. Allah did confer a great favour on the believers when He sent among them an apostle from among themselves, rehearsing unto them the Signs of Allah, sanctifying them, and instructing them in Scripture and Wisdom, while, before that, they had been in manifest error.
Masha-Allaah, Indeed.
I am also very grateful that Allaah gave me the opportunity to go to an islaamic school so that I may find Islaam for myself instead of blindly following others. AlHumdu-Lillaah.
'Alaykum As-Salaam Wa Rahmatullaahi Wa Barakaatuh.
Good question; you're the first to ask that . . . ;DIt's common sense; some people use "etc...", some use "ilh...", but they're not compatible in most cases; so I use " . . . " . . .
