Silsilat al-Ahadith al-Sahihah

The Noble Prophet (peace and blessings be upon him) said: "When my Companions are mentioned, remain silent; when the stars are mentioned, remain silent; and when the matter of destiny is mentioned, remain silent." This hadith has been narrated from Sayyiduna Abdullah bin Mas'ud, Sayyiduna Thawban, Sayyiduna Abdullah bin Umar (may Allah be pleased with them), and from Tawus as mursal.
