Asl wr wb, Sister this story came to my mind, so thought to share it with you Once a christian came to Shah Abdul Aziz Ra. ( son of Shah Waliullah Ra) and asked him: Your prophet Mohammad ( may peace be upon him ) was a favourite of Allah Swt and his prayers were answered. He loved his grandson dearly . Then why did he not ask Allah Swt to save him during the battle of Karbala from being martyred ? Shah Abdul Aziz Ra. analysing the situation tactfully answered the christian : Oh, Prophet did ask to save his grandson from being martyred but Allah Swt replied that since He could not save his own son ( Jesus ) from being crucified, how could He save his grandson : )
