السلام عليكم ورحمة الله وبركاته احسن الله اليك Can you mention what time the qailulah should be taken in general and what about on jumuah? Any benefits to know?

‎Qaylulah is a rest in the middle of the day, and Shaykh Ibn Uthaymin said it is shortly before Dhuhr. On Friday the Companions delayed it until after Jumu'ah, as Sahl said, "We would not take qaylulah or eat lunch except after Jumu'ah" (al-Bukhari and Muslim). Its benefit is rest for the body, which helps with night prayer.
