Ibn Kathir (Abridged)
Hafiz Ibn KathirThe Command to the Believers to have Taqwa and speak the Truth
Here Allah commands His servants to have Taqwa of Him, worshipping Him as if they can see Him, and toقَوْلاً سَدِيداً(speak (always) the truth.) meaning, to speak in a straightforward manner, with no crookedness or distortion. He promises them that if they do that, He will reward them by making their deeds righteous, i.e., enabling them to do righteous deeds, and He will forgive them their past sins. With regard to whatever sins they may commit in the future, He will inspire them to repent from them. Then He says:وَمَن يُطِعِ اللَّهَ وَرَسُولَهُ فَقَدْ فَازَ فَوْزاً عَظِيماً(And whosoever obeys Allah and His Messenger, he has indeed achieved a great victory.) meaning, he will be saved from the fire of Hell and will enjoy everlasting delights (in Paradise).
