What factors contribute to some Shia believers being born more blessed than others? Is this determined by their own actions, or is it solely by Allah's will?
Allah (SWT) Knows the whole past, present and future deeds. Those who will do more good according to the Knowledge of Allah, will be more blessed. So, it is determined by their actions and by the Will of Allah (SWT) Who is The Mist Merciful.
Wassalam.
