Sayyiduna Abu Umamah Bahili (may Allah be pleased with him) says: I was standing beneath the mount of the Messenger of Allah (peace and blessings be upon him) on the occasion of the Farewell Pilgrimage. The Prophet said many excellent things, among which was this: "Whoever among the People of the Book (a Jew or a Christian) becomes a Muslim will receive a double reward, and he will be given the same rights as we have, and the same responsibilities will be imposed upon him as are upon us. And whoever among the polytheists becomes a Muslim will receive a single reward, and he too will have the same rights as we have, and he will have to fulfill the same responsibilities as we fulfill."

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "There are three types of people whom Allah Almighty dislikes the most and who are most hateful to Him: one who commits heresy in the Sacred Sanctuary, one who seeks to revive the practices of ignorance in Islam, and one who strives to shed the blood of a person unjustly."

Sayyiduna Abdullah bin Umar (may Allah be pleased with them) says: I heard the Messenger (peace and blessings of Allah be upon him) say: "Swearing an oath by anyone other than Allah is shirk (associating partners with Allah)."

Lady Qateela bint Safiyyah (may Allah be pleased with her) from the tribe of Juhaina says: A Jewish scholar came to the Prophet (peace and blessings be upon him) and said: You people commit shirk because you say: "Whatever Allah wills and you will," and you swear by the Ka'bah. The Messenger of Allah (peace and blessings be upon him), upon hearing this, said: "You should say: Whatever Allah wills and then you will, and when swearing, say: By the Lord of the Ka'bah."

Sayyiduna Abdullah bin Umar (may Allah be pleased with them) narrates that the Noble Prophet (peace and blessings of Allah be upon him) said: "Swear by Allah, fulfill it, and speak the truth, because Allah dislikes swearing by other than Him."

Sayyidah Qutaylah bint Safi Juhaniyyah (may Allah be pleased with her) says: A Jewish scholar came to the Messenger of Allah (peace and blessings be upon him) and said: O Muhammad! You are the best of people, but if only you did not commit shirk? The Prophet (peace and blessings be upon him) said:“Subhan Allah! (How astonishing!) How is that?”He said: When you swear an oath, you say: By the Ka‘bah. The Prophet (peace and blessings be upon him) remained silent for a while and then said:“This man has spoken the truth. Now, whoever swears an oath should swear by the Lord of the Ka‘bah (and not by the Ka‘bah itself).”He then said: O Muhammad (peace and blessings be upon him)! You are very good people, but if only you did not set up equals with Allah! The Prophet (peace and blessings be upon him) said: Subhan Allah! How is that? He said: You say: Whatever Allah wills and you will. The Messenger of Allah (peace and blessings be upon him) remained silent for a while, then said:“This man has spoken the truth. If anyone says ‘Masha Allah’, he should say «ثُم شئت» (i.e., whatever Allah wills and then you will).”

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Avoid major sins, remain steadfast on the straight path, and give glad tidings (to the people)."

It is narrated from Sayyiduna Hudhayfah (may Allah be pleased with him), he states that the Messenger of Allah (peace and blessings be upon him) said: "Count all those who have accepted Islam." We said: O Messenger of Allah! Are you afraid for us, even though our number is between six hundred and seven hundred? The Messenger of Allah (peace and blessings be upon him) said: "You do not know (the reality of the situation), perhaps you will fall into trials." The narrator says: Then we were tested to such an extent that one of us had to pray secretly (that is, due to certain reasons, he could not pray openly).

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them) reports that the Noble Prophet (peace and blessings be upon him) was asked: Which religion is most beloved to Allah Almighty? He (peace be upon him) replied: "The religion of Islam, which is a gentle and easygoing Shari'ah."

It is narrated from Sayyiduna Mihjan bin Adra’ (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) received news that a certain person was performing long prayers in the mosque. The Prophet (peace and blessings be upon him) came to him, took hold of his shoulder, and said:“Allah Almighty has preferred ease for this Ummah and disliked hardship (he said this three times), whereas this servant has chosen hardship and abandoned ease.”
