It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that Allah Almighty revealed these verses: «﴿وَمَنْ لَمْ يَحْكُمْ بِمَا أَنْزَلَ اللّٰهُ فَأُولَئِكَ هُمُ الْكَافِرُونَ . . . فَأُولَئِكَ هُمُ الظَّالِمُونَ . . . فَأُولَئِكَ هُمُ الْفَاسِقُونَ﴾ [المائدة: 44-47] » “Those who do not judge by what Allah has revealed, they are disbelievers... they are wrongdoers... they are defiantly disobedient.”These were revealed concerning two groups of Jews. In the time of ignorance, one group had prevailed over the other, and they had agreed to a settlement with mutual consent that if a man from the dominant tribe killed someone from the subdued tribe, the blood money would be fifty wasqs, and if a man from the subdued tribe killed someone from the dominant tribe, the blood money would be one hundred wasqs. They remained upon this agreement until the Prophet (peace and blessings be upon him) came to Madinah. After the arrival of the Prophet (peace and blessings be upon him), both groups became subdued, but the Prophet (peace and blessings be upon him) did not wage war against them nor trample their lands; rather, he made a peace treaty with them. During this period, a man from the subdued tribe killed a man from the dominant tribe. The dominant tribe sent word to the subdued tribe, saying,“Send us one hundred wasqs as blood money.”The subdued tribe replied,“Can it ever be that among tribes whose religion is one, whose lineage is one, and whose city is one, the blood money for some is full and for others is half? Previously, we used to give you this amount out of fear and dread of you, but now that Muhammad (peace and blessings be upon him) has come, we cannot give you this blood money under any circumstances.”War was about to break out between the two groups when both agreed to appoint the Prophet (peace and blessings be upon him) as judge. Then the dominant tribe remembered and said,“By Allah! Muhammad (peace and blessings be upon him) will not grant you double the blood money, and what they are saying is correct, that they used to give us double the blood money out of fear, dread, and our dominance. Therefore, secretly send someone to Muhammad (peace and blessings be upon him) who can inform you of his opinion. If he grants you the blood money you desire, then appoint him as your judge, and if not, then avoid him and do not appoint him as your arbitrator.”So they secretly sent some people from among the hypocrites to the Prophet (peace and blessings be upon him) to find out his opinion and report back. When they reached the Prophet (peace and blessings be upon him), Allah Almighty informed His Messenger of all their details and intentions, and He revealed these verses: «﴿يَا أَيُّهَا الرَّسُولُ لَا يَحْزُنْكَ الَّذِينَ يُسَارِعُونَ فِي الْكُفْرِ مِنَ الَّذِينَ قَالُوا آمَنَّا . . . . . وَمَنْ لَمْ يَحْكُمْ بِمَا أَنْزَلَ اللّٰهُ فَأُولَئِكَ هُمُ الْفَاسِقُونَ﴾ [المائدة: 41-47] » “O Messenger! Let not those grieve you who hasten into disbelief, from among those who say, ‘We believe’... and those who do not judge by what Allah has revealed, they are defiantly disobedient.”Then Sayyiduna Ibn Abbas (may Allah be pleased with them both) said,“By Allah! This verse was revealed concerning these two groups, and Allah meant these two groups in this verse.”

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever listens to a group’s conversation which they wish to keep hidden from him, molten punishment will be poured into his ears on the Day of Resurrection. Whoever narrates a false dream will also be punished on the Day of Resurrection, and he will be ordered to tie two grains of barley together, but he will not be able to do so. And whoever makes images, he will be punished on the Day of Resurrection and will be told to put a soul into them, but he will not be able to do so."

Hakam bin A'raj says that once I went to the service of Sayyiduna Ibn Abbas (may Allah be pleased with them both) at the House of Siqayah. He was sitting, leaning on his cloak. I asked him to tell me something about the Day of Ashura. He said: In what regard are you asking about it? I said: Regarding fasting, that is, on which day should I fast? He said: When you see the crescent of Muharram, keep counting its days. When the morning of the ninth day comes, then fast. I asked: Did the Prophet (peace and blessings be upon him) fast in this way? He said: Yes.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "On the Day of Resurrection, this Black Stone will come in such a way that it will have two eyes with which it will see, and a tongue with which it will speak, and it will bear witness in favor of the person who kissed it with truth."

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that among the prisoners of Badr, there were some people who had nothing with which to pay ransom. The Prophet (peace and blessings be upon him) fixed their ransom in such a way that they should teach writing to the children of the Ansar. One day, a child came to his father crying. The father asked, "What happened?" He said, "The teacher hit me." He said, "Wicked one! You want to take revenge for Badr. From now on, you will never go to him again."

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that on the day of the Battle of Uhud, the Prophet (peace and blessings be upon him) ordered regarding the martyrs: "Remove the iron weapons and leather (armor) from them," and said: "Bury them with their blood in the same clothes."

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that an Ansari man became an apostate and joined the polytheists. Upon this, the following verse was revealed: «﴿كَيْفَ يَهْدِي اللّٰهُ قَوْمًا كَفَرُوا بَعْدَ إِيمَانِهِمْ . . . . .﴾ [آل عمران: 86] » "How shall Allah guide a people who disbelieved after their belief . . . . ." His people conveyed this verse to him, and he repented and returned. The Prophet (peace and blessings of Allah be upon him) accepted his repentance and let him go his way.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Wear white clothes, for they are the best of your clothes, and shroud your dead in them. And the best kohl among you is antimony (ithmid), for it sharpens the eyesight and grows the eyelashes."

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that while performing Tawaf of the House of Allah, the Prophet (peace and blessings be upon him) performed Ramal in three circuits; he would walk at his normal pace up to the Yemeni Corner, and when he reached the Black Stone, he would begin Ramal, and he performed four circuits at a normal pace, and this is Sunnah.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that once the Prophet (peace and blessings be upon him) was sitting in Masjid al-Haram facing the Black Stone, when suddenly he looked up towards the sky and smiled and said:“May Allah curse the Jews, for fat was made unlawful for them, but they melted it and made oil from it and began to sell it. Indeed, when Allah makes something unlawful for a people to eat, He also makes its price unlawful for them.”
