Hadith 31-183

وَبِهذَا الإسناد قالَ: قـالَ رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْـهِ وَآلِـهِ: مَن كُنْت مَوْلاهُ فَعَلِىٌّ مَوْلاهُ. اَللَّهُمَّ والَ مَن والاهُ وَعادَ مَن عاداهُ وَانصُر مَن نَصْرَه وَاخْذُلْ مَنْ خَذَلَهُ.

According to the same documentation, God’s Prophet (S) said, “Whoever I am the Master of, Ali is the Master of.” He then prayed and said, “Like whoever likes Ali and be the enemy of whoever is Ali’s enemy. Help whoever helps him and belittle whoever belittles him.”
