Narrated Ammar ibn Yasir:
The Messenger of Allah (saws) encamped at Ulat al-Jaysh and Aisha was in his company. Her necklace of onyx of Zifar was broken (and fell somewhere). The people were detained to make a search for that necklace until the dawn broke. There was no water with the people. Therefore AbuBakr became angry with her and said: You detained the people and they have no water with them.
Thereupon Allah, the Exalted, sent down revelation about it to His Apostle (saws) granting concession to purify themselves with pure earth. Then the Muslims stood up with the Messenger of Allah (saws) and struck the ground with their hands and then they raised their hands, and did not take any earth (in their hands). Then they wiped with them their faces and hands up to the shoulders, and from their palms up to the armpits.
Ibn Yahya added in his version: Ibn Shihab said in his tradition: The people do not take this (tradition) into account.
Abu Dawud said: Ibn Ishaq also reported it in a similar way. In this (version) he said on the authority of Ibn 'Abbas. He mentioned the words "two strikes" (i.e. striking the earth twice) as mentioned by Yunus. And Ma'mar also narrated on the authority of al-Zuhri "two strikes". And Malik said: From al-Zuhri from 'Ubaid Allah b. 'Abd Allah from his father on the authority of 'Ammar. Abu Uwais also reported it in a similar way on the authority of al-Zuhri. But Ibn 'Uyainah doubted it, he sometimes said: from his father, and sometimes he said: from Ibn 'Abbas. Ibn 'Uyainah was confused in it and in his hearing from al-Zuhri. No one has mentioned "two strikes" in this tradition except those whose names I have mentioned.

Narrated AbuUmayr ibn Anas:
AbuUmayr reported on the authority of his uncle who was from the Ansar (the helpers of the Prophet): The Prophet (saws) was anxious as to how to gather the people for prayer.
The people told him: Hoist a flag at the time of prayer; when they see it, they will inform one another. But he (the Prophet) did not like it. Then someone mentioned to him the horn.
Ziyad said: A horn of the Jews. He (the Prophet) did not like it. He said: This is the matter of the Jews. Then they mentioned to him the bell of the Christians. He said: This is the matter of the Christians. Abdullah ibn Zayd returned anxiously from there because of the anxiety of the Apostle (saws). He was then taught the call to prayer in his dream. Next day he came to the Messenger of Allah (saws) and informed him about it.
He said: Messenger of Allah, I was between sleep and wakefulness; all of a sudden a newcomer came (to me) and taught me the call to prayer. Umar ibn al-Khattab had also seen it in his dream before, but he kept it hidden for twenty days.
The Prophet (saws) said to me (Umar): What did prevent you from saying it to me?
He said: Abdullah ibn Zayd had already told you about it before me: hence I was ashamed.
Then the Messenger of Allah (saws) said: Bilal, stand up, see what Abdullah ibn Zayd tells you (to do), then do it. Bilal then called them to prayer.
AbuBishr reported on the authority of AbuUmayr: The Ansar thought that if Abdullah ibn Zayd had not been ill on that day, the Messenger of Allah (saws) would have made him mu'adhdhin.

Narrated `Abdullah bin Mas`ud:
Sa`d bin Mu`adh came to Mecca with the intention of performing `Umra, and stayed at the house of Umaiya bin Khalaf Abi Safwan, for Umaiya himself used to stay at Sa`d's house when he passed by Medina on his way to Sham. Umaiya said to Sa`d, "Will you wait till midday when the people are (at their homes), then you may go and perform the Tawaf round the Ka`ba?" So, while Sa`d was going around the Ka`ba, Abu Jahl came and asked, "Who is that who is performing Tawaf?" Sa`d replied, "I am Sa`d." Abu Jahl said, "Are you circumambulating the Ka`ba safely although you have given refuge to Muhammad and his companions?" Sa`d said, "Yes," and they started quarreling. Umaiya said to Sa`d, "Don't shout at Abi-l-Hakam (i.e. Abu Jahl), for he is chief of the valley (of Mecca)." Sa`d then said (to Abu Jahl). 'By Allah, if you prevent me from performing the Tawaf of the Ka`ba, I will spoil your trade with Sham." Umaiya kept on saying to Sa`d, "Don't raise your voice." and kept on taking hold of him. Sa`d became furious and said, (to Umaiya), "Be away from me, for I have heard Muhammad saying that he will kill you." Umaiiya said, "Will he kill me?" Sa`d said, "Yes,." Umaiya said, "By Allah! When Muhammad says a thing, he never tells a lie." Umaiya went to his wife and said to her, "Do you know what my brother from Yathrib (i.e. Medina) has said to me?" She said, "What has he said?" He said, "He claims that he has heard Muhammad claiming that he will kill me." She said, By Allah! Muhammad never tells a lie." So when the infidels started to proceed for Badr (Battle) and declared war (against the Muslims), his wife said to him, "Don't you remember what your brother from Yathrib told you?" Umaiya decided not to go but Abu Jahl said to him, "You are from the nobles of the valley (of Mecca), so you should accompany us for a day or two." He went with them and thus Allah got him killed.
