This issue is of the same type which I have mentioned in several places in my books, that the Arabs sometimes mention a single number of something, but by that number they do not intend to negate more than that.

Sayyiduna Miswar bin Makhramah رضي الله عنه and Marwan bin Hakam رضي الله عنه narrate that the Messenger of Allah set out in the year of Hudaybiyyah to visit the Sacred House (for Umrah), and he did not intend to fight. He took seventy camels with him for sacrifice, and the number of people was seven hundred, thus each camel was for ten people as a sacrifice. In the narration of Sayyiduna Jabir رضي الله عنه, it is mentioned that the number of Companions who participated in Hudaybiyyah was fourteen hundred.

Sayyiduna Miswar bin Makhramah (may Allah be pleased with him) and Janab Marwan (may Allah have mercy on him) narrate that the Noble Prophet (peace and blessings be upon him) set out in the year of Hudaybiyyah with more than one thousand companions. When he reached Dhul-Hulayfah, he adorned his sacrificial animals with garlands and marked them, and from there he entered into the state of Ihram for ‘Umrah. Then the rest of the hadith is mentioned. Imam Abu Bakr (may Allah have mercy on him) says that in the narration of Muhammad bin Ishaq, it is stated that the Messenger of Allah (peace and blessings be upon him) took seventy camels for sacrifice with him, and the number of companions was seven hundred. By this, he means that he sacrificed seventy camels on behalf of seven hundred individuals. It does not mean that the total number of companions who participated in the Treaty of Hudaybiyyah was seven hundred. This issue is of the same kind as when we say that by using the word "people" (al-nas), sometimes only some individuals are meant, not all people, as in the statement of Allah the Exalted: «‏‏‏‏الَّذِينَ قَالَ لَهُمُ النَّاسُ إِنَّ النَّاسَ قَدْ جَمَعُوا لَكُمْ» ‏‏‏‏ [ سورة آل عمران: 173 ] "The people said to them, 'Indeed, the people have gathered against you.'" Now, it is certain that not all disbelievers said this, nor did all people gather against them (even though the word "people" is used in both places). Similarly, the statement of Allah the Exalted: «‏‏‏‏ثُمَّ أَفِيضُوا مِنْ حَيْثُ أَفَاضَ النَّاسُ» ‏‏‏‏ [ سورة البقرة: 199 ] "And you should return from where the people return." It is also definite and certain that not all people returned from ‘Arafat. Therefore, by "afada al-nas" (the people return), Allah the Exalted means some people, not all people. This issue is quite lengthy and this is not the place to elaborate on it. The narration of Janab Sufyan bin ‘Uyaynah is a clear proof of the correctness of this interpretation, because it contains the words that the number of companions was more than one thousand. In this way, he has clarified that the number of the people of Hudaybiyyah was more than thirteen hundred, because the word "bidh‘" is used for numbers from three to ten (and Ibn ‘Uyaynah has mentioned one thousand and "bidh‘" as the number), in which it is stated that the number of companions at Hudaybiyyah was fourteen hundred. And this narration is similar to the narration in which it is stated that the number of companions at Hudaybiyyah was fourteen hundred. And this narration also explicitly states that the number of companions was fourteen hundred. This is evidence that in the narration of Ibn Ishaq, the words that the number of companions was seven hundred mean some of the companions who were with the Messenger of Allah (peace and blessings be upon him) at Hudaybiyyah, not their total number. Based on this interpretation and these evidences, it becomes clear that the Prophet sacrificed one camel on behalf of ten companions, and some companions, seven individuals, participated in the sacrifice of one camel or one cow. Therefore, the statement of Sayyiduna Jabir (may Allah be pleased with him) that "seven of us participated in the sacrifice of a camel, and seven participated in the sacrifice of a cow," means some of the people of Hudaybiyyah, not all of them. And in the narration of Sayyiduna Miswar bin Makhramah (may Allah be pleased with him) and Janab Marwan (may Allah have mercy on him), it is stated that ten individuals participated in the sacrifice of a camel, meaning that out of fourteen hundred companions, seven hundred companions participated in seventy camels, ten by ten. This number is half of the companions who participated at Hudaybiyyah, not the total number.

Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that we were with the Messenger of Allah (peace be upon him) on a journey when Eid al-Adha came, so seven people participated in the sacrifice of a cow and ten people participated in the sacrifice of a camel.

After the narration of Sayyiduna Abu Dharr (may Allah be pleased with him) from the Noble Prophet (peace and blessings be upon him), these words are mentioned: He was asked, "Which slave is best to set free?" The Prophet (peace and blessings be upon him) replied: "The one who is more valuable and more excellent in the eyes of his owners." After this narration, it is stated: "Every thing whose loss causes a person more distress—if that thing is spent in the way of Allah, then its reward and recompense will also be much greater."
