HAZRAT IMAM SADIQ (AS) has said: ``Some of the Jews accompanied with HAY-IBN-AKHTAB and his brother went to the prophet and said: `according to the NUMERICAL ALPHABET, (ABJAD ALIF=1, LÄM=30, MIM=40) that make up a total of 71; which indicates that your Islam and Muslim people will not last more than 71 years.'' In order to prevent misinterpretation of the words and verses and making a play-toy of phrases; the prophet said to them: ``Why have you counted only A-L-M, while there are many other abbreviated letters in Qurän such as A-L-M-S and A-L-R, etc.? If you think that these letters count for the duration of Muslim community, why don't you then add all of them together? Therefore the purpose of the letters are not so as you think.''
