The supremacy of Ali’s (ع) faith over any other faith
Omar ibn Khattab narrates that the Messenger of Allah (ص) said:
﴿ لَوْ أَنَّ السَّمَاوَاتِ وَالْأَرْضَ وُضِعَتَا فِي كَفَّةٍ وَإِيمَانُ عَلِيٍّ فِي كَفَّةٍ لَرُجِّحَ إِيمَانُ عَلِيٍّ ﴾
"If the heavens and the earth were placed in one scale and the faith of Ali in another, the faith of Ali will undoubtedly be heavier than the other” [1]
The faith of the Commander of the Faithful is to such magnitude where he himself says:
﴿ لَوْ كُشِفَ الْغِطَاءُ مَا ازْدَدْتُ يَقِيناً ﴾
“If the covering is uncovered, it will not add to my certainty (faith).” [2]
