Hadith 2259
Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates the statement of Sayyiduna Suhaib (may Allah be pleased with him): I passed by the Prophet (peace and blessings of Allah be upon him) while he was performing prayer. I greeted him with salam, and he replied to me with a gesture. The narrator says: I think these words are also in the narration: "He replied with a gesture of his finger."
