Khalifah bin Khayyat mentioned the lineage of Abdullah bin al-Arqam (may Allah be pleased with him) and said that Abdullah bin al-Arqam was the scribe of the Prophet (peace and blessings be upon him), of Abu Bakr and of Umar (may Allah be pleased with them both).

Al-Qasim bin Muhammad narrates from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that he said: A man's letter came to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) said to Abdullah bin al-Arqam (may Allah be pleased with him): "Write the reply on my behalf." So he wrote its reply, then read it out to him (peace and blessings be upon him). He (peace and blessings be upon him) prayed for him: 'Asabta wa ahsanta, Allahumma waffiqhu' (You have written correctly and done very well; O Allah, grant him success). Then when Umar (may Allah be pleased with him) became caliph, he used to consult him. This hadith has an authentic (sahih) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

Al-Zubayr bin Bakkar relates that Abdullah bin al-Arqam bin Abd Yaghuth was in charge of the public treasury (Bayt al-Mal) during the caliphate of Umar (may Allah be pleased with him) and in the early part of the caliphate of Uthman (may Allah be pleased with him) until his death. And he had the honour of being a Companion.

Hisham bin Urwah narrates from his father, who narrates from Sayyiduna Abdullah bin al-Arqam (may Allah be pleased with him), that he said: The Messenger of Allah (peace and blessings be upon him) said: "When the prayer is about to begin and one of you needs to relieve himself, he should first relieve himself." This hadith has an authentic (sahih) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

Ibn Ishaq, while listing the names of those from Banu Jusham bin al-Harith and Zayd bin al-Harith (these two were twin brothers) who were present at the Battle of Badr and the Pledge of Aqabah, related that among them was Abdullah bin Zayd bin Abd Rabbih bin Tha'labah (may Allah be pleased with him). He is the one who was shown the call to prayer (adhan) in a dream; then he brought it to the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) ordered that it (the adhan) be put into practice.

Yahya bin Bukayr relates that Abdullah bin Zayd (may Allah be pleased with him), the Companion of the adhan (who saw it in a dream), had the kunyah Abu Muhammad.

It is reported from Urwah, concerning those from Banu Jusham bin al-Harith and Zayd bin al-Harith (who were both twin brothers) who were present at the Battle of Badr and the Pledge of Aqabah, that among them were Abdullah bin Zayd bin Abd Rabbih bin Tha'labah bin Zayd bin al-Harith bin al-Khazraj and his brother Hurayth bin Zayd (may Allah be pleased with them). And Abdullah bin Zayd (may Allah be pleased with him) is the one who was shown the call to prayer (adhan) in a dream.

Muhammad bin Umar relates that the kunyah of Abdullah bin Zayd bin Abd Rabbih bin Tha'labah bin Zayd bin al-Harith was Abu Muhammad. According to all the narrators, Abdullah bin Zayd (may Allah be pleased with him) was among the seventy of the Ansar who were present (for the pledge) on the night of Aqabah. He took part with the Messenger of Allah (peace and blessings be upon him) in the Battles of Badr, Uhud, al-Khandaq and all the campaigns. In the campaign of the Conquest of Makkah the banner of Banu al-Harith bin al-Khazraj was with him, and he is the Companion who was shown the adhan in a dream.

Muhammad bin Abdullah bin Zayd relates that he said: "My father Abdullah bin Zayd died in Madinah in the year 32 AH, when he was 64 years old, and the Commander of the Faithful Uthman bin Affan (may Allah be pleased with him) led his funeral prayer." Imam al-Hakim says: Abdullah bin Zayd (may Allah be pleased with him) is famous for the hadith of the adhan, which the scholars of Islam have circulated with acceptance, and it was not recorded in the two Sahihs because of the disagreement of the narrators in its chains. The best narration on this is that of Sa'id bin al-Musayyab. Some of our Imams imagined that Sa'id did not meet Abdullah bin Zayd, but that is not so, for Sa'id bin al-Musayyab was among those who acted as mediators for reconciliation between Sayyiduna Ali and Sayyiduna Uthman (may Allah be pleased with them both), and Abdullah bin Zayd died in the last period of the caliphate of Sayyiduna Uthman (may Allah be pleased with him). The hadith of al-Zuhri from Sa'id bin al-Musayyab is well known; it was narrated by Yunus bin Yazid, Ma'mar bin Rashid, Shu'ayb bin Abi Hamzah, Muhammad bin Ishaq and others. As for the narrations of the people of Kufah on this topic, they all revolve around the hadith of Abd al-Rahman bin Abi Layla: some of them said: "From Sayyiduna Mu'adh bin Jabal or Abdullah bin Zayd", and some said: "From Abd al-Rahman, from Abdullah bin Zayd". As for the narrations of Abdullah bin Zayd's descendants from him through their forefathers, their chains are not sound. And Abdullah bin Zayd (may Allah be pleased with him) also narrated hadiths from the Messenger of Allah (peace and blessings be upon him) other than this (adhan) hadith:

Abu Bakr bin Muhammad bin Amr bin Hazm narrates from Sayyiduna Abdullah bin Zayd bin Abd Rabbih (may Allah be pleased with him) (he is the one who was shown the adhan in a dream) that he came to the Messenger of Allah (peace and blessings be upon him) and said: "O Messenger of Allah! This garden of mine is charity, and it is (endowed) for Allah and His Messenger." Then his parents came and said: "O Messenger of Allah! It (the garden) was our only means of livelihood." So the Messenger of Allah (peace and blessings be upon him) returned that garden to the two of them. Then both of them died, and afterwards this son of theirs inherited that garden.
