Translation:

23. That is (the Bounty) whereof Allah gives Glad Tidings to His Servants who believe and do righteous deeds. Say: "No reward do I ask of you for this except the love of those near of kin." And if anyone earns any good We shall give Him an increase of good in respect thereof: for Allah is Oft-Forgiving Most Ready to appreciate (service).

Notes (Tafseer)

4559. Heaven may be pictured to our minds in various forms. This is one of the highest, and Allah announces it freely to the righteous.

4560. No sort of tangible reward does the prophet of Allah ask for proclaiming the Glad Tidings of Allah. But at least he has the right to ask that his kith and kin should not persecute him and put all sorts of obstacles in his way, as did the Quraish against the holy Prophet.

4561. Cf. xxxv. 29-30, and notes 3915 (for increase) and 3917 (for Allah's appreciation of service).
