[4:175] As for those who believe in God, and hold fast to Him, He will surely admit them to mercy from Him, and bounty, and He will guide them to Him by a straight path.
He will surely admit them to mercy from Him: the particle indicating the future (the letter sīn) indicates that He will protect them at the time of death on account of their faith (īmān) in what is to come, just as He has honored them with knowledge and faith in the present.
[4:175 cont'd] and He will guide them to Him by a straight path.
This guidance is His honoring them in knowing that this guidance is a bounty from God for them, not because they deserve it, and not because of their seeking, effort, toil or pains.
