This Is My Faith - Al-fatlawi, Ali - الصفحة ٢٦٠ - the Imams (PBUT)?
This Hadith clearly shows that the love for those loved by the Allah entails faith and vice versa.
Anwar: Would you please give more Hadith in this regard?
Hasan: There are many Hadith regarding the love and resent:
The Prophet Mohammad (PBUH) once asked his companions “What bond of faith is the strongest?” Some said “Allah and His Messenger know better” and some others suggested “Saying prayers, fasting, pilgrimage to Mecca and holy wars”. The Prophet (PBUH) said “All you mentioned have their own merits, but the strongest bond of faith is to love for the sake of Allah, to resent for the sake of Allah, to follow the people in authority and to renounce the enemies of Allah”.
It is reported that Jesus Christ (PBUH) said “seek the affection of the Lord through detesting the wrongdoers, seek the favor of the Lord through avoiding them and seek the grace of the Lord through resenting them”.
