The advice from Allaah to the first and the last is to command with
taqwaa; Allaah mentions:
{
And verily, We have recommended to the people of the Scripture
before you, and to you (O Muslims) that you (all) fear Allâh
}
[An Nisaa 4:131]
Likewise, this was the advice of the Messenger of Allaah (sallallahu
alayhi wa sallam) to Muaadh ibn Jabal when he sent him to Yemen.
He said to him: Have taqwaa of Allaah
wherever you are and follow a bad deed up with a good one and it shall
wipe it out and have good character in dealing with the people.[1]
The meaning of taqwaa is carrying out what Allaah commands
and staying away from what He forbids. Allaah promises the Muttaqeen
those who have taqwaa, an abundance of rewards in this world
and the hereafter.
In one verse of the Quraan Allaah says: {Verily, the
Muttaqûn (the pious) will be in place of Security (Paradise).
Among Gardens and Springs} [ Ad-Dukhan 44:51-52]
Allaah mentions:
{Verily, for the Muttaqûn, there will be a success (Paradise);
Gardens and vineyards} [ An-Nabaa 78:31-32]
Allaah says: {Verily, the Muttaqûn (the pious. See V.2:2),
will be in the midst of Gardens and Rivers (Paradise). In a seat of
truth (i.e. Paradise), near the Omnipotent King (Allâh, the One,
the All-Blessed, the Most High, the Owner of Majesty and Honour).} [
Al-Qamar 54:54-55]
And Allaah says:
{
And whosoever fears Allâh and keeps his duty to Him,
He will make a way for him to get out (from every difficulty). And He
will provide him from (sources) he never could imagine
} [At-Talaaq
65:2-3]
There are many aayaat and ahaadeeth concerning the reward for taqwaa.
