Silsilat al-Ahadith al-Sahihah

Sayyiduna Bashir (may Allah be pleased with him) says: I asked the Messenger of Allah (peace and blessings be upon him): I will fast on Friday and will not speak to anyone on that day? The Prophet (peace and blessings be upon him) said: "Do not fast on Friday, unless you fast on several days and Friday happens to be among them (then there is no harm). As for your issue of not speaking to anyone, by my life! Speaking good and forbidding evil is better for you than remaining silent."
