Kutoka kwa Anas bin Malik (Radhi za Allah ziwe juu yake) reported: "The Mjumbe wa Allah (Rehema na amani za Allah ziwe juu yake) used to leave off observing Saum (kufunga) during a month until we thought that he would not observe Saum at all during it; and (sometimes) he would observe Saum till we began to think that he would not omit any day of that month. If one wished to see him performing Salat during the night, he could do that; and if one wished to see him sleeping at night, he could do that.."

Anas (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) used to leave off observing Saum (fasting) during a month until we thought that he would not observe Saum at all during it; and (sometimes) he would observe Saum till we began to think that he would not omit any day of that month. If one wished to see him performing Salat during the night, he could do that; and if one wished to see him sleeping at night, he could do that..
