Silsilat al-Ahadith al-Sahihah

Sayyiduna Abdullah (may Allah be pleased with him) says: I heard Sayyiduna Buraidah (may Allah be pleased with him) say, he said: I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "There are five things which only Allah knows: Indeed, with Allah alone is the knowledge of the Hour, He sends down the rain, and He knows what is in the wombs. No one knows what he will earn tomorrow, nor does anyone know in which land he will die. Remember, Allah alone is All-Knowing and All-Aware." (Surah Luqman: 34)
