Are there any Ahadith regarding wearing of a head covering by men (1) at all times, (2) during Salaat (prayer), (3) while reading or listening Qur'an, (4) while eating?

There are a large number of Ahaadith establishing that it was the practice%0D%0Aof Nabi (Sallallaahu Alayhi Wasallam) to use a turban, a few of which are%0D%0Abelow.%0D%0A%0D%0AHadhrat Ubaadah (Radhiallaahu Anhu) reports that Nabi (Sallallaahu Alayhi%0D%0AWasallam) said, 'Make a practice of tying turbans since it is a hallmark of%0D%0Athe angels.' (Mishkaat)%0D%0A%0D%0AHadhrat ibn Abbaas (Radhiallaahu Anhu) reports that Nabi (Sallallaahu Alayhi%0D%0AWasallam) would sometimes wear a Topee (hat) with a turban and sometimes%0D%0Awithout a turban. Sometimes, he would wear a turban without the headgear. He%0D%0Awould wear a white Yemeni Topee which was sewn. During battles, he would%0D%0Awear a Toppee (headgear) that covered his ears. (Turban, Kurta, Topee, pg.18%0D%0Afrom Masnad of Riyaani and Taareekh of ibn Asaakir)%0D%0A%0D%0AAllaamah Munaawi (Radhiallaahu Anhu) comments that wearing the Topee without%0D%0Athe turban refers to Nabi's (Sallallaahu Alayhi Wasallam) occasional%0D%0Apractice while at home. He (Sallallaahu Alayhi Wasallam) would not venture%0D%0Aoutdoors without the turban. It can be ascertained from this commentary that%0D%0Ait was his opinion that Nabi (Sallallaahu Alayhi Wasallam) would always wear%0D%0Aa turban in public.%0D%0A%0D%0AFrom the above discussion, it can be deduced that Nabi (Sallallaahu Alayhi%0D%0AWasallam) always had his head covered.%0D%0A%0D%0Aand Allah Ta'ala Knows Best%0D%0A%0D%0AMufti Bilaal Cassim%0D%0AFATWA DEPT.%0D%0A%0D%0ACHECKED AND APPROVED CORRECT: Mufti Ebrahim Desai
