4. Ali ibn Ibrahim has narrated from his father, from al-Nawfaliy from al-Sakuniy who has said the following
“Abu ‘Abd Allah (a.s.), has said that Amir al-Mu’minin (a.s.), has said, ‘The Messenger of Allah sent me to Yemen and said to me, “You must not fight anyone before calling him to Allah. I swear by Allah, if Allah guides through you one man it will be more excellent for you than all the things on which the sun shines and sets. You, O Ali, will have his guardianship.’””
