Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: Sometimes the Prophet (peace and blessings be upon him) would use the miswak four times during the night.
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, Musa bin Mutayr, who is extremely da'if (weak).
