Sayyiduna Ali (may Allah be pleased with him) had a strange habit: he would wear warm clothes in the winter and cool clothes in the summer. Someone said to my father, "If you ask him about this, perhaps he will answer." So, when my father asked, Sayyiduna Ali (may Allah be pleased with him) replied: "Once, on the day of the Battle of Khaybar, the Prophet (peace and blessings be upon him) sent a messenger to me. I was suffering from an eye disease, so I said, 'O Messenger of Allah! I have an eye ailment.' Upon hearing this, the Prophet (peace and blessings be upon him) put his saliva in my eyes and prayed: «اَللّٰهُمَّ أَذْهِبْ عَنْهُ الْحَرَّ وَالْبَرْدَ» 'O Allah! Remove from him the heat and the cold.' From that day until today, I have never felt heat or cold." On that occasion, the Prophet (peace and blessings be upon him) also said, "I will give this flag to the person who loves Allah and His Messenger, and who is beloved in the sight of Allah and His Messenger; he will not flee." The noble Companions (may Allah be pleased with them) began to present themselves for this purpose, but the Prophet (peace and blessings be upon him) granted that flag to me.

On one occasion, Sayyiduna Ali (may Allah be pleased with him) addressed the people and said: Do you not feel any shame or honor that your women go out of their homes? I have learned that your women go out to the markets and mingle among crowds of strong men (their bodies touch those of men and they have no idea which part of their body is touching which part of a man's body).

Shuraih bin Hani (may Allah have mercy on him) says that I asked Sayyida Aisha Siddiqa (may Allah be pleased with her) a question regarding wiping over the socks, so she said: "Ask this question to Sayyiduna Ali (may Allah be pleased with him), he has more knowledge about this issue because he used to accompany the Prophet (peace and blessings be upon him) during travels." So I asked Sayyiduna Ali (may Allah be pleased with him), and he said that the Prophet (peace and blessings be upon him) said: "The traveler is permitted to wipe over the socks for three days and three nights, and the resident for one day and one night."

And the Prophet, peace and blessings be upon him, forbade wailing.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that I heard the Prophet (peace and blessings of Allah be upon him) say: "Whoever, while performing ghusl in a state of major impurity, leaves even an area equal to a single hair where water does not reach, Allah the Exalted will deal with him in such and such a manner in Hell." From that very moment, I became hostile towards my hair.
