"Those who believe and work righteousness, for them is forgiveness and a sustenance most generous. (50)
Tafsir
The real matter is that man is going to enter a world where it is only believers and pious people who will have eternal comfort and not those who arrogantly ignore the Truth. The real purpose of the Islamic call is to warn people of this coming Day. The sole duty of the giver of the call is to warn people. All other matters relate to God alone, for it is He alone who is at the helm of affairs.
