Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) said: Sayyiduna Suraqah bin Malik bin Ju'shum (may Allah be pleased with him) stood up and said: "Is this Umrah of ours only for this year, or forever and ever?" So the Messenger of Allah (peace and blessings be upon him) interlaced his fingers one into the other and said: "Umrah has entered into Hajj," twice, "no, rather forever and ever."
