Being assiduous in doing everything prescribed in Islam and carrying out its pillars in the proper manner, with sincerity, is the path to success and prosperity, and a means of salvation from the terrors of the Day of Resurrection. In this hadith, Talhah ibn ‘Ubaydullah (may Allah be pleased with him) narrates that a man from Najd – which is a region of Arabia between the Hejaz and Iraq – came to the Prophet (blessings and peace of Allah be upon him). That man was Dimam ibn Tha‘labah; his hair was unkempt because of the rigours of travel, and he had a loud voice, but nothing he said could be understood until he drew close to the Messenger of Allah (blessings and peace of Allah be upon him). It turned out that he was asking about the teachings of Islam, so the Prophet (blessings and peace of Allah be upon him) responded by explaining that the first duty of Islam that was required of him was the five prayers, which are to be offered every day and night. He said: Do I have to offer any prayers other than these five prayers? The Prophet (blessings and peace of Allah be upon him) replied: You do not have to offer any other prayers, unless you voluntarily do some of the regular Sunnah and other Sunnah prayers, which are encouraged (mustahabb) and you will be rewarded for doing them, but you will not be punished for not doing them. Then the Prophet (blessings and peace of Allah be upon him) told him that he had to fast Ramadan. Fasting means refraining, with the intention of worship, from food, drink, sexual activity and other things that break the fast, from the break of dawn until the sun sets. He said: Do I have to do anything else? He said: You do not have to do anything else, unless you do it voluntarily, fasting some days other than Ramadan, for they are encouraged and you will be rewarded for doing that. Then the Prophet (blessings and peace of Allah be upon him) told him about zakah, which is an obligatory, financial act of worship, to be given on every type of wealth that meets the minimum threshold, as defined in Islamic teachings, when one full lunar (or Hijri) year has passed since acquiring that wealth, giving one quarter of one tenth. One should also give zakah on an‘am animals [camels, cattle and sheep] and other livestock; zakah on crops, fruits, and trade goods; and zakah on rikaz, which is buried treasure that is brought out of the earth and, it was said, minerals and metals, on the basis of their nisab (minimum threshold), to be given at the time at which their zakah becomes due. Giving zakah in the proper manner to those who are entitled to it brings increased blessing (barakah) to wealth, and brings great reward in the hereafter, whereas being stingy and withholding it from those who are entitled to it brings bad consequences in this world and the hereafter, as has been explained in many texts of the Qur’an and Sunnah. Zakah is to be given to those who are entitled to it, who are mentioned in the verse: {Zakah expenditures are only for the poor and for the needy and for those employed to collect [zakah] and for bringing hearts together [for Islam] and for freeing captives [or slaves] and for those in debt and for the cause of Allah and for the [stranded] traveler - an obligation [imposed] by Allah. And Allah is Knowing and Wise} [al-Tawbah 9:60]. The man asked: Do I have to do anything other than that? He said: No, unless you give something else in charity voluntarily, and you will be rewarded for that, but it is not obligatory and you will not be sinning if you do not do it. Then the man turned and left, swearing by Allah that he would not do any supererogatory (nafil) deeds in addition to these obligatory duties, and he would not omit any of them. The Messenger of Allah (blessings and peace of Allah be upon him) said: “He will succeed if he is speaking the truth.” In other words, if he means what he says, and he does these pillars [of Islam] sincerely for the sake of Allah (may He be exalted), then he will attain Paradise and be saved from the Fire, even if he does not do any supererogatory actions. This hadith indicates that if a person limits himself to the obligatory religious duties, as prescribed in the religious texts, then he will succeed, but this does not mean that it is not prescribed for him to do some voluntary acts of worship, because the voluntary actions will complete the obligatory actions (and make up for any shortcomings in them) on the Day of Resurrection..
