From The Saying of The Messenger of Allah (pbuh) (29)

Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (PBUH) said, "When one of you leads the Salat (prayer), he should not prolong it because the congregation includes those who are feeble, ill or old". One version adds: "those who have to attend to work'') While offering prayers alone, you may pray as long as you like" (Al-Bukhari and Muslim)

Commentary:
This Hadith shows us that the messenger of Allah (pbuh ) is more merciful to us from our mothers and our fathers . He (pbuh ) loves his followers very nuch and looks after the old,the ill and the weak of his Ummah (nation ).He (pbuh ) gives instructions to the Imams who lead the congregation Salat (prayer) not to prolong the prayer for the sake of them but when they pray alone they can pray as long as they can

عن عبد الله بن عمر( رضي الله عنه) قال :
"أن رسول الله صلى الله عليه وسلم قال : ( المسلم أخو المسلم ، لا يظلمه ولا يسلمه ، ومن كان في حاجة أخيه كان الله في حاجته ، ومن فرج عن مسلم كربة فرج الله عنه كربة من كربات يوم القيامة ، ومن ستر مسلما ستره الله يوم القيامة ) .

Ibn `Umar (May Allah be pleased with them) reported: Messenger of Allah (PBUH) said, "A Muslim is a brother of another Muslim. So he should not oppress him nor should he hand him over to (his Satan or to his self which is inclined to evil). Whoever fulfills the needs of his brother, Allah will fulfill his needs; whoever removes the troubles of his brother, Allah will remove one of his troubles on the Day of Resurrection; and whoever covers up the fault of a Muslim, Allah will cover up his fault on the Day of Resurrection" (Al-Bukhari and Muslim)

Commentary:
In this Hadith the messenger of Allah advises all Muslims to live as a big family because Muslims are all brothers .Every member should not oppress his brother or offers him to the enemy of believers the satan but he should be with his brother against satan.He should cooperate with his brother in the time of need and if his brother was in trouble he should help him find a solution to this problem.If he does that he will find the reward from Allah in the day of Resurrection .Allah will help him find solutions for his problems there. If he covers up his brother's faults, Allah will cover his faults there.

قال رسول الله صلي الله عليه وسلم : " انصر أخاك ظالما أو مظلوما . فقال رجل : يا رسول الله ، أنصره إذا كان مظلوما ، أفرأيت إذا كان ظالما كيف أنصره ؟ قال : تحجزه ، أو تمنعه ، من الظلم فإن ذلك نصره"

خلاصة حكم المحدث: [صحيح]
The messenger of Allah (pbuh ) said :
"Help your brother, whether he is an oppressor or is oppressed". A man enquired: "O Messenger of Allah! I help him when he is oppressed, but how can I help him when he is an oppressor?'' He (PBUH) said, "You can keep him from committing oppression. That will be your help to him" (Al-Bukhari and Muslim)
Commentary :
1) This is a wonderful Hadith.It tells us how intelligent was the messenger of Allah (pbuh ). How he was a model teacher in teaching his followers. He (pbth) sometimes uses the suspense way in attracting their attention when He (pbuh) said : "Help your brother, whether he is an oppressor or is oppressed" They were surprised and one of them said : How can I help him when he is an oppressor? " then the messenger of Allah said : "You can keep him from committing oppression. That will be your help to him" . I think that the messenger of Allah meant to make this dialogue between Him and his companions and this was one of the ways that the messenger of Allah in teaching his companions and this is nowadays a very modern way in teaching .
2) Islam doesn't support oppression but it supports the justice even it was against ourselves.Allah said in the Quran :
۞ يَا أَيُّهَا الَّذِينَ آمَنُوا كُونُوا قَوَّامِينَ بِالْقِسْطِ شُهَدَاءَ لِلَّهِ وَلَوْ عَلَىٰ أَنْفُسِكُمْ أَوِ الْوَالِدَيْنِ وَالْأَقْرَبِينَ ۚإِنْ يَكُنْ غَنِيًّا أَوْ فَقِيرًا فَاللَّهُ أَوْلَىٰ بِهِمَا ۖفَلَا تَتَّبِعُوا الْهَوَىٰ أَنْ تَعْدِلُوا ۚوَإِنْ تَلْوُوا أَوْ تُعْرِضُوا فَإِنَّ اللَّهَ كَانَ بِمَا تَعْمَلُونَ خَبِيرًا. (4/135)
"O ye who believe! stand out firmly for justice, as witnesses to Allah, even as against yourselves, or your parents, or your kin, and whether it be (against) rich or poor: for Allah can best protect both. Follow not the lusts (of your hearts) lest ye swerve and if ye distort (justice) or decline to do justice, verily Allah is well-acquainted with all that ye do" (4/135)
3) I hope that Allah (pbth) collect us in the companionship of Muhammad (pbuh ) and his companions in the supreme paradise .Ameen.
