On a par with Abu Jahal, ranking with those who are branded eternally in history's pages on account of their atrocious treatment of the Prophet, was one of his uncles, a son of Abu Muttalib, surnamed Abu Lahab, "The Man Vowed to Hell-fire." Mohammad was preaching one day on the hill of Safa, in the midst of a crowd of inhabitants of that region, when Abu Lahab interrupted him rudely. 'Mayst thou be annihilated!' he bawled; 'thou who hast called us together to listen to such nonsense!' To this insult the following surah of the Qur'an (CXI) replies: "_Let the hands of Abu Lahab perish, and let himself perish! * His wealth and his gains shall avail him not. * Burned shall he be at the fiery flame, * And his wife laden with the fire-wood, * On her neck a rope of twisted palm-fibre._" This Surah, quickly becoming renowned, increased Abu Lahab's resentment and probably had even more effect on that of his wife, Umm Jemil, who found herself attacked therein in a way that was as annoying as it was deserved. To be nicknamed "carrier of fire-wood" was past endurance; but had she not, on one occasion, strewn the path of Mohammad with thorny branches; had not her tongue lit up the fires of hatred with the faggots of calumny that she hawked about everywhere? The odious couple resorted shamelessly to the vilest acts, daily throwing heaps of filth on the terrace of Mohammad's house or in front of his door, for he was their neighbour. Worked up or terrorised by these fanatics, most of the dwellers in Makkah repulsed the Prophet or avoided him. Children and wastrels pursued him with their jibes in the street. He was perfectly indifferent to such provocations. What was it all to him? Nothing more than a passing breeze. He never even seemed to notice the persons who acted thus; he only looked at those he hoped to convert. [Sidenote: THE INCIDENT OF THE BLIND MAN] It happened one day when Mohammad had taken in hand some of the most noted townsmen who were beginning to be moved by his arguments, that a blind pauper, Ibn Umm Maktum, came forward, and humbly begged to be granted a small share of the knowledge vouchsafed to the Prophet by Allah. Engrossed in his discussion with the citizens whose conversion he so ardently desired; fearing, too, to miss an opportunity which might never occur again, Mohammad was seized with a fit of momentary vexation and replied curtly to the blind man, who stumbled away sorrowfully without having been enlightened.
