Sayyiduna Ibn Abbas (may Allah be pleased with them both) said concerning the statement of Allah, the Lord of the worlds, "Then whoever hastens (to leave) in two days, there is no sin upon him, and whoever delays, there is no sin upon him" [Surah al-Baqarah: 203]: Whoever hastens in two days will be forgiven, and whoever delays until the three days will be forgiven as well. Da'if (weak): Qudamah's condition is unknown (majhul al-hal), and al-Dahhak did not meet Sayyiduna Ibn Abbas (may Allah be pleased with them both).
