"And if they intend to deceive thee, then surely Allah is sufficient for thee. He it is Who strengthened thee with His help and with the believers, And He has united their hearts. If thou hadst spent all that is in the earth, thou couldst not have united their hearts, but Allah united them. Surely He is Mighty, Wise. O Prophet, Allah is sufficient for thee and those who follow thee of the believers."
