It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said to me: Do not follow one glance with another glance; the first glance is forgiven, but you are not permitted the second.

(Second chain) The Noble Prophet (peace and blessings be upon him and his family) said: O Ali! There is a treasure for you in Paradise, you will reside at both edges of Paradise, therefore do not cast a second glance after the first; indeed, you are permitted the first glance, but not the second.

It is narrated from Sayyiduna Buraidah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him and his family) said to Sayyiduna Ali (may Allah be pleased with him): Do not follow one glance with another glance; the first glance is forgiven, but you are not permitted the second.

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Allah Almighty has written the share of adultery for the son of Adam, he will inevitably get it. The adultery of the eye is looking, then various (spiritual) ailments confirm it. The adultery of the tongue is speaking. The heart desires, and the private parts either confirm all these matters or deny them.

Narrated by Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Both eyes commit adultery, both hands commit adultery, both feet commit adultery, and the private part also commits adultery.

Narrated by Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him and his family) said: Every son of Adam has his share of adultery; the adultery of the eyes is looking, the adultery of the hands is touching, the adultery of the feet is walking (towards it), the adultery of the mouth is kissing, and the heart desires and wishes for it, and then the private parts either confirm or deny these matters. Then Sayyiduna Abu Hurairah (may Allah be pleased with him) made a circle of ten with his fingers and inserted the index finger of the other hand into it and said: The flesh and blood of Abu Hurairah bears witness to this.

Narrated by Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Every eye commits adultery.
