The Messenger of Allah (may Allah's peace and blessings be upon him) once said to me: "Get near to me," and I did
Authentic hadithعن أبي زيد الأنصاري رضي الله عنه قال: قال لي رسول الله صلى الله عليه وسلم : «اقتَرِب منِّي»، فاقتربتُ منه، فقال: «أَدْخِلْ يدك فامْسَح ظهري» ، قال: فأدْخلتُ يدي في قميصه، فمسَحتُ ظهْره، فَوَقَع خاتَم النبوة بين إصبعي، قال: فسُئل عن خاتَم النبوة، فقال: «شَعْرات بيْن كتِفيْه».
Abu Zayd al-Ansāri (may Allah be pleased with him) reported: The Messenger of Allah (may Allah’s peace and blessings be upon him) once said to me: "Get near to me," and I did. Hence, he asked me to put my hand (underneath his shirt) to massage his back. When I began massaging his back, my fingers accidentally touched the seal of prophet-hood. He (Abu Zayd) was asked about the seal of prophet-hood and replied: "It consisted of hair between his shoulders."
