Muhammad (s.a.a.w.) preached to the people to trust in Allah (swt). His whole life was a sublime example of the precept. In the loneliness of Makkah, in the midst of persecution and danger, in adversity and tribulations, and in the thick of enemies in the battles of Uhud and Hunain, complete faith and trust in Allah (swt) appears as the dominant feature in his life. However great the danger that confronted him, he never lost hope and never allowed himself to be unduly agitated. Abu Talib knew the feelings of the Quraish when the Prophet (s.a.a.w.) started his mission. He also knew the lengths to which the Quraish could go, and requested the Prophet (s.a.a.w.) to abandon his mission, but the latter calmly replied,
"Dear uncle, do not go by my loneliness. Truth will not go unsupported for long. The whole of Arabia and beyond will one day espouse its cause." [Ibn Hisham, Sirat-ur-Rasul]
Muhammad (s.a.a.w.) was the most far removed among his people from the love of money or wealth. He encouraged his followers to be industrious, make an honest living and discouraged them from seeking charity. He did not condemn wealth and the wealthy, however, he feared for his followers and encouraged them to not allow it to corrupt them or obsess them.
Muhammad (pbuh) himself could have been the most wealthy man in the history of Arabia, however, he preferred to live simply and use his wealth in that which pleased God. As the leader of the Islamic nation, he received great wealth, however, he hated for this wealth to remain in his home for more than a day without having distributed it in charity. At times he would distribute tens or hundreds of thousands of "dinars" at a time as soon as he received them. He lived according to his sayings:
"O my Lord, indeed, true life is only the afterlife" and "What have I to do with this life? The similitude of me and this life is as a traveler who stopped to take shelter in the shade of a tree and then arose and left it"
Urwah narrated that Aisha (the wife of Muhammad, pbuh) said to me,
"O my nephew! We used to see the crescent, and then the crescent, and then the crescent, in this way we saw three crescents in two months and no fire (for cooking) used to be lit in the houses of Allah's Messenger (pbuh). I said, "O my aunt! Then what use to sustain you?" Aisha said, "[These two]: dates and water." (Narrated by Al-Bukhari)
Abu Tharr narrated that Allah's Messenger (pbuh) said,
"If I had gold equal to the mountain of Uhud, it would not please me that any of it should remain with me after three nights (i.e. I would spend all of it in Allah's cause) except what I would keep for repaying debts." (Narrated by Al-Bukhari)
Jabir ibn Abdullah narrated:
"The messenger of Allah was never asked for something and then he said 'no' (he never refused a request)" (Narrated by Al-Bukhari)
1638. Ibn `Umar (May Allah be pleased with them) said: The Messenger of Allah (PBUH) forbade shaving a part of the head.
[Al-Bukhari and Muslim].
1639. Ibn `Umar (May Allah be pleased with them) said: The Messenger of Allah (PBUH) saw a boy, some portion of whose head was shaved and some of it was left out. He prohibited them from that and said, "Shave the whole of it or leave the whole of it.''
Commentary: This order of Prophet (PBUH) was based on the reason that that hair-style was then in vogue among the Jews and Christian priests and ascetics. This style was also popular with the group which was given to mischief and disobedience. This is, however, permissible in exceptional circumstances. In any case, either one should shave the hair completely or keep them in such a style that there is no resemblance with women.
1640. `Abdullah bin Ja`far (May Allah be pleased with them) said: The Prophet (PBUH) gave respite for three days to the family of Ja`far (after his martydom). Then he came and said, "Don't weep for my brother after this day.'' He said, "Bring all of my nephews to me.'' We were accordingly brought as if we were chickens. Then he said, "Call for me a barber.'' He directed him to shave our heads which he did.
Commentary: Ja`far was the cousin of the Prophet (PBUH) and he was martyred in the battle of Mu'tah. Although martyrdom is an honour but even then the bereaved family does feel the shock of the loss. For this reason, the Prophet (PBUH) permitted them to give vent to their grief for three days. It should not, however, be taken to mean that he allowed them to lament and wail, because that is prohibited. What he actually allowed them was the natural weeping which does occur when people come for condolence and speak of the deceased. Such expression of grief is permissible after a period of three days also.
Therefore, what the Prophet (PBUH) had advised them was not in the nature of unlawful but natural. The children of the deceased called themselves "chickens'' as they were greatly enervated by the tragedy. This Hadith has been mentioned here to confirm the validity of shaving the hair of the head, especially of children, although keeping bobbed hair is more meritorious because the Prophet (PBUH) himself did so. Bobbed hair are cut short and allowed to hang loosely.
1641. `Ali (May Allah be pleased with him) said: The Messenger of Allah (PBUH) prohibited a woman from shaving her head.
Commentary: This Hadith is also included in At-Tirmidhi but Sheikh Al-Albani has regarded it "Da`if'' (weak). Please see Ahadith Ad-Da`ifah. However, in order to avoid resemblance with men, this prohibition for women will stand. If it is required on medical ground then it will be permissible.
