I used to practice money exchange, and I asked Zaid bin 'Arqam about it, and he narrated what the Prophet said in the following: Abu Al-Minhal said, "I asked Al-Bara' bin `Azib and Zaid bin Arqam about practicing money exchange. They replied, 'We were traders in the time of Allah's Apostle and I asked Allah's Apostle about money exchange. He replied, 'If it is from hand to hand, there is no harm in it; otherwise it is not permissible."

The Prophet fought nineteen Ghazwas and performed only one Hajj after he migrated (to Medina), and did not perform another Hajj after it, and that was Hajj-ul-Wada`,' Abu 'Is-haq said, "He performed when he was in Mecca."

A partner of mine sold some Dirhams on credit in the market. I said, "Glorified be Allah! Is this legal?" He replied, "Glorified be Allah! By Allah, when I sold them in the market, nobody objected to it." Then I asked Al-Bara' bin `Azib (about it) he said, "We used to make such a transaction when the Prophet came to Medina. So he said, 'There is no harm in it if it is done from hand to hand, but it is not allowed on credit.' Go to Zaid bin Al- Arqam and ask him about it for he was the greatest trader of all of us." So I asked Zaid bin Al-Arqam., and he said the same (as Al-Bara) did."

The Annwar said, "O Allah's Apostle! Every prophet has his own followers and we have followed you. So will you invoke Allah to let our followers be considered from us (as Ansar too)?" So he invoked Allah accordingly.

It has been narrated on the authority of Zaid b. Arqam that the Messenger of Allah (may peace be upon him) fought nineteen battles and after the Migration performed only one Pilgrimage called Hajjat-ul-Wada'.

In the lifetime of the Prophet we used to speak while praying, and one of us would tell his needs to his companions, till the verse, 'Guard strictly your prayers (2.238) was revealed. After that we were ordered to remain silent while praying.

This hadith has been narrated on the authority of Zaid b. Arqam through another chain of transmitters.

I asked Zaid bin Al-Arqam, "In how many Ghazawat did you take part in the company of Allah's Apostle?" He replied, "Seventeen." I further asked, "How many Ghazawat did the Prophet fight?" He replied, "Nineteen."

We used to speak while in prayer. One of us used to speak to his brother (while in prayer) about his need, till the Verse was revealed:-- "Guard strictly the (five obligatory) prayers, especially the middle (the Best) (`Asr) Prayer and stand before Allah with obedience (and not to speak to others during the prayers)." Then we were ordered not to speak in the prayers.

Yahya related to me from Malik from Zayd ibn Aslam that his father said, "Abdullah ibn al-Arqam said, 'Show me a riding-camel which the amir al-muminim can give me to use.' I said, 'Yes. One of the sadaqa camels.' Abdullah ibn al-Arqam said, 'Would you want a stout man on a hot day to wash for you what is under his lower garment and its folds, and then give it to you to drink?' I was angry and said, 'May Allah forgive you! Why do you say such things to me?' Abdullah ibn al-Arqam said, 'Sadaqa is the impurities of people which they wash off themselves.' "

I asked Al-Bara' bin `Azib and Zaid bin Arqam about money exchanges. Each of them said, "This is better than I," and both of them said, "Allah's Apostle forbade the selling of silver for gold on credit. "

Once, while I was sitting beside Zaid bin Al-Arqam, he was asked, "How many Ghazwat did the Prophet undertake?" Zaid replied, "Nineteen." They said, "In how many Ghazwat did you join him?" He replied, "Seventeen." I asked, "Which of these was the first?" He replied, "Al-`Ashira or Al- `Ashiru."

`Abdullah bin Al-Fadl told me that Anas bin Malik said, "I was much grieve over those who had been killed in the Battle of Al-Harra. When Zaid bin Arqarr heard of my intense grief (over the killed Ansar), he wrote a letter to me saying that he heard Allah's Apostle saying, O Allah! Forgive the Ansar and the Ansar children. The subnarrator, Ibn Al-Fadl, is not sure whether the Prophet also said, And their grand-children." Some of those who were present, asked Anas (about Zaid). He said, "He (Zaid) is the one about whom Allah's Apostle said, 'He is the one whose sound hearing Allah testified.'
