Who sponsored the Messenger, may God bless him and grant him peace, after the death of his mother

The answer is:  His grandfather, Abd al-Muttalib

After the death of his mother, Amina bint Wahb received the Messenger of God - may God bless him and grant him peace - and was looked after by his grandfather Abdul Muttalib. Abdul Muttalib provided the necessary care and support to the Prophet, and ensured that he was able to live a healthy and fulfilling life. After the death of Abdul Muttalib, his uncle Abu Talib assumed the care of the Messenger of God, may God bless him and grant him peace. Abu Talib provided the Prophet's physical needs and spiritual guidance throughout his life.
