The one who takes unlawful tolls will not enter Paradise

Sayyiduna Uqbah bin Amir (may Allah be pleased with him) narrates: I heard the Messenger of Allah (peace and blessings be upon him) say: "The one who collects unjust taxes (sahib maks) will not enter Paradise." Yazid bin Harun says: What is meant by it is the unjust 'ashshar (toll collector).

Umm al-Mu'minin Sayyidah Umm Salamah (may Allah be pleased with her) narrates that while the Prophet (peace and blessings be upon him) was in her house, with some of his Companions sitting with him talking, a man came and said: "O Messenger of Allah, how much is the zakah on such-and-such an amount of dates?" The Messenger of Allah (peace and blessings be upon him) said: "Such-and-such." The man said: "So-and-so transgressed against me and took such-and-such from me," that is, he took one sa' more. The Messenger of Allah (peace and blessings be upon him) said: "Then how will it be with you when those who transgress against you even more severely than this come to collect from you?" The people began discussing it and the matter weighed heavily on them, until one of them said: "O Messenger of Allah, if a man is away from you with his camels, livestock and crops, and he pays the zakah of his wealth, but the due is exceeded against him, what should he do while he is absent?" The Messenger of Allah (peace and blessings be upon him) said: "Whoever pays the zakah of his wealth willingly, for the pleasure of Allah and the Home of the Hereafter, and conceals nothing of his wealth, establishes the prayer and pays the zakah, and then (unjustly) his right is transgressed, and he takes up his weapon and fights for the sake of his right and is killed, he is a martyr."

Aslam narrates that in the year of al-Ramadah (the year of famine), when the land was struck by drought, Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) wrote to Amr bin al-As, the governor of Egypt: "From the servant of Allah, Umar, Commander of the Believers, to al-As bin al-As: By my life, you do not care, so long as you and those with you grow fat, that I and those with me grow thin from hunger. Help, help!" Amr bin al-As wrote back: "Peace (be upon you). To proceed: Here I am, here I am at your service! A caravan is coming to you whose first camel will be with you and its last with me; moreover, I hope to find a way to send (provisions) by sea as well." When the first caravan arrived, Umar (may Allah be pleased with him) called Sayyiduna al-Zubayr (may Allah be pleased with him) and said: "Go out with the head of this caravan and take it towards Najd, and bring to me as many households as you are able to bring; and for those you cannot bring, order that each household be given a camel with its load. Tell them to wear two garments, to slaughter the camel and melt down its fat, to dry its meat and make footwear from its hide; then let them take a handful of dried meat, a handful of fat and a handful of flour and cook it, and let them eat until Allah grants them provision." Al-Zubayr (may Allah be pleased with him) refused to go, so Umar (may Allah be pleased with him) said: "By Allah, you will not find an opportunity like this (for good) until you leave this world." Then he called another man, I think it was Talhah, and he too refused. Then he called Sayyiduna Abu Ubaydah bin al-Jarrah (may Allah be pleased with him), and he went out for this task. When he returned, Umar (may Allah be pleased with him) sent him a thousand dinars. Abu Ubaydah said: "O Ibn al-Khattab, I did not work for you; I worked only for Allah, and I will not take anything for it." Umar (may Allah be pleased with him) said: "The Messenger of Allah (peace and blessings be upon him) also gave to us for some tasks he sent us on, which we disliked, but the Messenger of Allah (peace and blessings be upon him) did not accept our refusal. So, O man, accept it and use it to help you in your worldly needs." So Abu Ubaydah bin al-Jarrah (may Allah be pleased with him) accepted it.
