(V.21:91) It is said that Jibrael (Gabriel) had merely breathed in the sleeve of Maryam’s (Mary) shirt and thus she conceived.
(V.21:94) See the footnote of (V.9:121).
(V.21:98) When the following Statement of Allâh عز وجل was revealed: "Certainly you (disbelievers) and that which you are worshipping now besides Allâh are (but) fuel for Hell! (Surely), you will enter it."
The Quraish pagans were delighted and said: "We are pleased to be with our gods in the Hell-fire, as the idols will be with the idolaters (in the Hell-fire), and therefore ‘Îsâ (Jesus), the son of Maryam (Mary) will be with his worshippers (i.e. in the Hell-fire) and so on.
So (to clear the misunderstanding) Allâh عز وجل revealed the following Verse (to deny and reject their claim): "Verily, those for whom the good has preceded from Us, they will be removed far therefrom (Hell). [e.g. ‘Îsâ (Jesus), the son of Maryam (Mary); ‘Uzair (Ezra)]." [The Qur’ân, Verse 21:101].
(V.21:100) Ibn Mas‘ûd رضي الله عنه recited this Verse and then said: "When those (who are destined to remain in the Hell-fire forever) will be thrown in the Hell-fire, each of them will be put in a separate Tabût (box) of Fire, so that he will not see anyone punished in the Hell fire except himself." Then Ibn Mas‘ûd recited this Verse (21:100). [Tafsir Ibn Kathir, Tabari and Qurtubî].
