Sometime in 1999, a construction electrician received a new work assignment from his union. The man, Sinclair Hejazi Abdus-Salaam, was told to report to 2 World Trade Center, the southern of the twin towers.
In the union locker room on the 51st floor, Mr. Abdus-Salaam went through a construction worker’s version of due diligence. In the case of an emergency in the building, he asked his foreman and crew, where was he supposed to reassemble? The answer was the corner of Broadway and Vesey.
Over the next few days, noticing some fellow Muslims on the job, Mr. Abdus-Salaam voiced an equally essential question: “So where do you pray at?” And so he learned about the Muslim prayer room on the 17th floor of the south tower.
He went there regularly in the months to come, first doing the ablution known as wudu in a washroom fitted for cleansing hands, face and feet, and then facing toward Mecca to intone the salat prayer.
On any given day, Mr. Abdus-Salaam’s companions in the prayer room might include financial analysts, carpenters, receptionists, secretaries and ironworkers. There were American natives, immigrants who had earned citizenship, visitors conducting international business — the whole Muslim spectrum of nationality and race.
