Narrated An-Nu'man bin Bashir: I heard Allah's Apostle saying, 'Both legal and illegal things are evident but in between them there are doubtful (suspicious) things and most of the people have no knowledge about them. So whoever saves himself from these suspicious things saves his religion and his honor. And whoever indulges in these suspicious things is like a shepherd who grazes (his animals) near the Hima (private pasture) of someone else and at any moment he is liable to get in it. (O people!) Beware! Every king has a Hima and the Hima of Allah on the earth is His illegal (forbidden) things. Beware! There is a piece of flesh in the body if it becomes good (reformed) the whole body becomes good but if it gets spoilt the whole body gets spoilt and that is the heart.

Narrated Abu Jamra: 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 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 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 Apostle! 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 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 said, "It means: 1. To testify that none has the right to be worshipped but Allah and Muhammad is Allah's Apostle. 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 mentioned the container of wine and he meant the wine itself). The Prophet further said (to them): "Memorize them (these instructions) and convey them to the people whom you have left behind."

Thus, in action are included faith, ablution, prayer, zakat, Hajj, fasting, and all the commands. And (in Surah Bani Isra'il) Allah said: O Prophet! Say that everyone acts according to his own way, that is, his own intention. And (because of this) if a person, with the intention of reward and understanding it as Allah's command, spends on his family, then he also receives the reward of charity for it. And when Makkah was conquered, the Noble Prophet (peace and blessings be upon him) said that (now the series of migration has ended), but the series of jihad and intention remains.

Narrated 'Umar bin Al-Khattab: Allah's Apostle 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."

Narrated Abu Mas'ud: The Prophet 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.

Narrated Sa'd bin Abi Waqqas: Allah's Apostle said, "You will be rewarded for whatever you spend for Allah's sake even if it were a morsel which you put in your wife's mouth."

And Allah has said (in Surah At-Tawbah): "As long as they remain sincere to Allah and His Messenger."

Narrated Jarir bin Abdullah: I gave the pledge of allegiance to Allah's Apostle for the following: 1. offer prayers perfectly 2. pay the Zakat (obligatory charity) 3. and be sincere and true to every Muslim.

Narrated Ziyad bin'Ilaqa: I heard Jarir bin 'Abdullah (Praising Allah). On the day when Al-Mughira bin Shu'ba died, he (Jarir) got up (on the pulpit) and thanked and praised Allah and said, "Be afraid of Allah alone Who has none along with Him to be worshipped.(You should) be calm and quiet till the (new) chief comes to you and he will come to you soon. Ask Allah's forgiveness for your (late) chief because he himself loved to forgive others." Jarir added, "Amma badu (now then), I went to the Prophet and said, 'I give my pledge of allegiance to you for Islam." The Prophet conditioned (my pledge) for me to be sincere and true to every Muslim so I gave my pledge to him for this. By the Lord of this mosque! I am sincere and true to you (Muslims). Then Jarir asked for Allah's forgiveness and came down (from the pulpit).
