There is another Hadith to the effect that every important work which is not started with the invocation "Bismillah" is devoid of Allah's Grace. Sheikh Al-Albani's opinion about these two Ahadith is that their text is confused and its authority is weak. He has, however, regarded it as acceptable "Mursal" (Ahadith narrated by a student of a Companion deleting the Companion's name). (For details please see Irwa-ul-Ghalil, vol. I, 1,2). In any case, it is desirable to begin every good work with the Glorious Name of Allah and His Praise.
