Sayyiduna Bashir bin Sa'd (may Allah be pleased with him), a Companion of the Messenger of Allah (peace and blessings be upon him), said that the Messenger of Allah (peace and blessings be upon him) said: "The place of a believer in relation to a believer is the place of the head in relation to the body: whenever the body is in pain, the head feels pain for it, and whenever the head is in pain, the rest of the body feels pain."

Sayyiduna al-Nu'man bin Bashir (may Allah be pleased with him) narrates from his father, Sayyiduna Bashir bin Sa'd (may Allah be pleased with him), from the Prophet (peace and blessings be upon him), that he (peace and blessings be upon him) said: "May Allah have mercy on a servant who heard my words and preserved them, for many a bearer of knowledge (fiqh) is not himself a man of understanding, and many a bearer of knowledge conveys it to one who has more understanding than he."
"There are three things over which the heart of a believer never harbours rancour: making deeds sincerely for Allah, giving sincere counsel to the rulers of the Muslims, and holding fast to the community (jama'ah) of the Muslims."
