Why Allah send darood on Prophet Muhammad(saw)?

>

إِنَّ اللَّهَ وَمَلَائِكَتَهُ يُصَلُّونَ عَلَى النَّبِيِّ ۚ يَا > أَيُّهَا الَّذِينَ آمَنُوا صَلُّوا عَلَيْهِ وَسَلِّمُوا > تَسْلِيمًا

> > Allah and His Angels send blessings on the Prophet: O ye that believe! > Send ye blessings on him and salute him with all respect. **Surah Ahzaab verse 56** I have to think about this from a long time why Allah has to send his blessing toward Muhammad (saw). I mean Allah have All the power of the world and he accepts all blessing of mankind and every other living thing, then why He have to send his blessing?
I am sorry if I did not get the proper translation cause I don't know how to speak Arabic.
