Sahih Muslim Book 41, Hadith Number 7029.

Al-Sha’bi reported: We visited Fatima b. Qais and she served us fresh dates which are called Rutab and she also served us barley. I asked her about that woman in whose case three divorces had been pronounced as to how much time she should count as the waiting period. She said: My husband pronounced three divorces in my case and Allah’s Messenger (may peace be upon him) permitted me to spend any waiting period in my family. (It was during this period) that announcement was made for the people to observe prayer in the bigger Mosque. I went there along with people and I was in the front row meant for women and it was adjacent to the last row of men and I heard Allah’s Messenger (may peace be upon him) deliver sermon sitting on the pulpit. He said: The cousin of Tamim (Dari) sailed in the ocean. The rest of the hadith is the same but with this addition: “(I see) as if I am looking to Allah’s Apostle (may peace be upon him) pointing his rod towards the land (and saying): It is Taiba, i.e. Medina.”
