Allah's Messenger (ﷺ) said, "The reward of deeds depends upon the intention and every person will get the reward according to what he has intended. So whoever emigrated for Allah and His Apostle, then his emigration was for Allah and His Apostle. And whoever emigrated for worldly benefits or for a woman to marry, his emigration was for what he emigrated for."
Sahih al-Bukhari Book 2, Hadith 47
← Previous Hadith I used to sit with Ibn 'Abbas and he made me sit on his sitting place. He requested me to stay with him in order that he might give me a share from his property. So I stayed with him for two months. Once he told (me) that when the delegation of the tribe of 'Abdul Qais came to the Prophet, the Prophet (ﷺ) asked them, "Who are the people (i.e. you)? (Or) who are the delegate?" They replied, "We are from the tribe of Rabi'a." Then the Prophet (ﷺ) said to them, "Welcome! O people (or O delegation of 'Abdul Qais)! Neither will you have disgrace nor will you regret." They said, "O Allah's Messenger (ﷺ)! We cannot come to you except in the sacred month and there is the infidel tribe of Mudar intervening between you and us. So please order us to do something good (religious deeds) so that we may inform our people whom we have left behind (at home), and that we may enter Paradise (by acting on them)." Then they asked about drinks (what is legal and what is illegal). The Prophet (ﷺ) ordered them to do four things and forbade them from four things. He ordered them to believe in Allah Alone and asked them, "Do you know what is meant by believing in Allah Alone?" They replied, "Allah and His Apostle know better." Thereupon the Prophet (ﷺ) said, "It means:

1. To testify that none has the right to be worshipped but Allah and Muhammad is Allah's Messenger (ﷺ).

2. To offer prayers perfectly

3. To pay the Zakat (obligatory charity)

4. To observe fast during the month of Ramadan.

5. And to pay Al-Khumus (one fifth of the booty to be given in Allah's Cause).

Then he forbade them four things, namely, Hantam, Dubba,' Naqir Ann Muzaffat or Muqaiyar; (These were the names of pots in which Alcoholic drinks were prepared) (The Prophet (ﷺ) mentioned the container of wine and he meant the wine itself). The Prophet (ﷺ) further said (to them): "Memorize them (these instructions) and convey them to the people whom you have left behind."

Sahih al-Bukhari Book 2, Hadith 46 Next Hadith → The Prophet (ﷺ) said, "If a man spends on his family (with the intention of having a reward from Allah) sincerely for Allah's sake then it is a (kind of) alms-giving in reward for him.
