Ibrahim's Emigration, the Test of the Sacrifice of Isma`il, and how Allah blessed Him

Allah tells us that after He helped His close friend Ibrahim, peace be upon him, against his people, and after Ibrahim gave up hoping that they would ever believe despite all the mighty signs that they had witnessed, he emigrated away from them, and said:

وَقَالَ إِنِّى ذَاهِبٌ إِلَى رَبِّى سَيَهْدِينِ - رَبِّ هَبْ لِى مِنَ الصَّـلِحِينِ

Which son was to be slaughtered? Was it Sayyidna Ismai1 (علیہ السلام) ? Or, was it Sayyidna Ishaq (علیہ السلام) ?

The Tafsir of the verses cited above has been described on the assumption that the son who was to be slaughtered was Sayyidna Ismail (علیہ السلام) . But, the truth of the matter is that there is a severe difference of opinion among commentators and historians about it. That this son was Sayyidna Ishaq (علیہ السلام) has been reported from among the Sahabah by Sayyidna ` Umar, Sayyidna ` Ali, Sayyidna ` Abdullah Ibn Mas` ud, Sayyidna ` Abbas, Sayyidna ` Abdullah Ibn ` Abbas and Sayyidna Ka'b al-Ahbar ؓ ، and from among the Tabi` in by Said Ibn Jubayr, Qatadah, Masriq, ` Ikrimah, 'Ata', Muqatil, Zuhri and Suddiyy رحمۃ اللہ علیہم . Counter to this is the narrations from Sayyidna ` Ali, Sayyidna Ibn ` Abbas, Sayyidna ` Abdullah Ibn ` Umar, Sayyidna Abu Hurairah and Sayyidna Abu-t-Tufayl ؓ from among the Sahabah, and Said Ibn Musaiyyab, Said Ibn Jubayr, Hasan al-Basri, Mujahid, ` Umar Ibn ` Abd-ul-` Aziz, Sha'bi, Muhammad Ibn Ka` b al-Qurazi from among the Tabiin from whom it has been reported that that this son was Sayyidna Ismail (علیہ السلام) . It is to be noted that the names of Sayyidna ` Ali, Ibn ` Abbas and Sa;id ibn Jubayr appear in both groups. This is because reports of both views are attributed to them. (Usmani)
