Comparing Islam and Christianity on dealing with apostates

The Quran teaches:

They but wish that ye should reject Faith, as they do, and thus be on the same footing (as they): So take not friends from their ranks until they flee in the way of God (From what is forbidden). But if they turn renegades, seize them and slay them wherever ye find them; and (in any case) take no friends or helpers from their ranks;- (4:89)

The Bible teaches:

1 Timothy 1:20 Of whom is Hymenaeus and Alexander; whom I have delivered unto Satan, that they may learn not to blaspheme. (for the renegade apostates)

2 Timothy 1:15 This thou knowest, that all they which are in Asia be turned away from me; of whom are Phygellus and Hermogenes.

2 Timothy 1:16 The Lord give mercy unto the house of Onesiphorus; for he oft refreshed me, and was not ashamed of my chain:

2 Timothy 1:17 But, when he was in Rome, he sought me out very diligently, and found me.

2 Timothy 1:18 The Lord grant unto him that he may find mercy of the Lord in that day: and in how many things he ministered unto me at Ephesus, thou knowest very well.

(For an ex Christian who is not a renegade and instead did good to a Christian)

Apostle Saint Paul prayed over to an apostate who is not a renegade that someday God will have mercy on him on the Judgment Day.
