在正统哈里发时期,存放公款的地方逐渐被称为"公库"(Bayt Al-Mal)。伊本·萨阿德在《大事记》(Al-Tabaqat)中,转述萨希勒·伊本·阿布·哈思玛及其他人的说法:"阿布·伯克尔在阿尔-萨尼赫有一所房子,没有人看守。有人对他说:'你为什么不派人看守它?'他说:'它有锁。'他将其中的财物陆续分发出去,直至空空如也。当他迁往麦地那时,便将其搬走,放在自己家中。"
欣纳德在《禁欲篇》(Al-Zuhd)中以良好的传述链,转述安纳斯的话:"有一个人来见欧麦尔,说:'信士们的领袖啊!请资助我,我想去参加圣战。'欧麦尔说:'拉着他的手,带他到公库去,让他取所需的钱财。'"
拜哈基在《大圣训集》(Al-Sunan Al-Kubra)中转述阿卜杜拉·伊本·瓦迪阿的话,伊本·哈贾尔认定该段传述可靠:"阿布·胡宰法的仆人萨利姆,是我们家一位名叫萨勒玛·宾特·叶尔的女子的仆人。她在蒙昧时期释放了他。他在叶麻玛战役中阵亡后,他的遗产被送到欧麦尔·伊本·哈塔卜那里。欧麦尔便召见了瓦迪阿·伊本·希西姆,说:'这是你仆人的遗产,你比别人更有权得到它。'他说:'信士们的领袖啊,真主使我们不需要它。我们的女主人无条件地释放了他,所以我们不想因他的事而使自己蒙羞(或使自己受损)。'于是欧麦尔将他的遗产放入公库。"
拜哈基和达里米转述,伊本·哈兹姆认定该段传述可靠:"苏夫扬·伊本·阿卜杜拉·伊本·拉比阿·塞given·萨given·萨给给" 阿布杜拉·本·阿慕尔叙述说:"在奥斯曼执政时,有一名奴隶去世,没有任何亲属。于是他下令将其财产交入公库(Bayt Al-Mal)。"达里米(Al-Darimi)和伊本·艾布·沙伊巴(Ibn Abi Shaybah)都有此段记载。
伊本·阿卜杜·巴尔(Ibn ‘Abd Al-Barr)在《Al-Istidhkar》中引述安纳斯·伊本·西林(Anas Ibn Sirin)的话:"阿里过去分配公库中的资金,直到公库空了,然后他会将其洗净,并坐在里面。"
At the time of the righteous Khulafaa’, the place in which funds were kept came to be known as Bayt Al-Mal. Ibn Sa‘d mentioned in Al-Tabaqat from Sahl Ibn Abu Hathmah and others: “Abu Bakr used to have a house in Al-Sanh not guarded by anybody. So it was said to him, ‘Why do you not put somebody to guard it?’ He said, ‘It has a lock.’ He used to give out that which was in it until it became empty. When he moved to Madinah, he moved it and placed it in his house.” Hinad narrated in Al-Zuhd with a good chain from Anas, he said: “A person came to Umar and said, ‘O Leader of the Believers! Support me for I want to go in Jihad. Umar replied, ‘Hold his hand and take him to Bayt Al- Mal so he can take the funds he wants.” In Al-Sunan Al-Kubra by Al-Bayhaqi, which was authenticated by Ibn Hajar from ‘Abd Allah b. Wadi‘ah, said: “Salim, the servant of Abu Hudhayfah, was a servant to a woman from us called Salma bint Ye’ar, she freed him in her days of Jahiliyyah. When he was killed in Al- Yamamah, his heritage was brought to Umar Ibn Al-Khattab. So he called upon Wadi‘ah Ibn Khidham and said, ‘This is the heritage of your servant, and you deserve it more.’ He said, ‘O Leader of the Believers. Allah has made us of no need to him. Our woman has freed him unrestricted; so we do not want to bring disgrace to ourselves, (or to bring loss upon us) from his matter.’ So, Umar put his inheritance wealth in the Bayt Al-Mal.” Al- Bayhaqi and Al-Darimi narrated, and Ibn Hazm authenticated it: “Sufyan b. ‘Abd Allah b. Rabi’ah Al-Thaqafi found a leather bag and brought it to Umar b. Al-Khattab. He said, ‘Announce it for one year; and if it was recognised (by someone) then give it (to them), otherwise it is yours.’ No body recognised it, so he met him the next year and mentioned it to him. Umar said, ‘It is yours, for the Messenger of Allah (pbuh) ordered us to do that.’ He said, ‘I do not want it.’ Umar took it and put it in the Bayt Al-Mal.” Al- Darimi and Ibn Abi Shaybah narrated from ‘Abd Allah b. Amr who said: “A servant passed away at the time of Uthman without having a relative. So, he ordered that his wealth be put in Bayt Al- Mal.” Ibn ‘Abd Al-Barr narrated in Al-Istidhkar from Anas Ibn Sirin “Ali used to divide the funds until the Bayt Al-Mal became empty, then he would wash it and sit inside.”.
