20 – ʿAbd Allah narrated to us; he said: ʿAbd al-Raḥmān ibn ʿAbd Allah al-Bāhilī narrated to me; he said: Sufyān ibn ʿUyaynah informed us, from ʿUbayd Allah ibn ʿUmar, from Nāfiʿ, from Ṣafiyyah, who said: “Madinah quaked in the time of ʿUmar (may Allah be pleased with him). He said, ‘People, what is this? How quickly you have introduced new things! If it happens again, I will not live among you here.’”
