[16].Surah An-Nahl [The Bees]: Ayat 72

Ayat 72. And Allah has made for you wives of your own kind, and has made for you, from your wives, sons and grandsons, and has bestowed on you good provision. Do they then believe in false deities and deny the Favour of Allah (by not worshipping Allah Alone). 

Hazrat Umm Salamah (May Allah be pleased with her) reported: I asked Messenger of Allah  [SAWW](PBUH), "Would I be rewarded for what I spend on Abu Salamah's sons? For I can't let them go here and there (to beg people).'' Messenger of Allah (PBUH) replied, "Spend on them and you will be rewarded for what you spend on them".

[Al-Bukhari Book 02, Chapter 24, Hadith # 546].

Lesson : as mentioned above in Surah An-Nahl Ayat 72. and has bestowed on you good provision".Although parents spend money on their children out of their natural love for them, Allah is so Gracious that He not only rewards them for it, but He gives it in greater proportion than what they spend on other meritorious items.
