Torah describing this Ummah

Hadhrat Abdullah bin Amr (r.a.a.) once asked Hadhrat Ka'b (r.a.a.) to describe Rasulullah (s.a.w.) and his Ummah to him. Hadhrat Ka'b (r.a.a.) said, "I have found them (described as follows) in Allah Ta'ala's book (the Torah): 'Verily Ahmad (s.a.w.) and his Ummah shall praise Allah Ta'ala abundantly who will praise Allah Ta'ala (by saying "Al Hamdu Lillah") during favourable and adverse conditions. They will exalt Allah Ta'ala (by saying "Allahu Akbar") when ascending an incline and glorify Him (by saying "Subhan'Allah") when descending from a raised place. Their call (the Adhan) shall resound in the skies and during their salaah they will communicate (with Allah Ta'ala) with humming (whispering) sounds like the sound of bees against a rock. They will form rows in their (congregational) salaah just as the angels form rows and will form rows in battle as they do in salaah. When they go to battle in the path of Allah Ta'ala (for Allah Ta'ala's pleasure), the angels will be before them and behind them with powerful spears. When they present themselves for battle in Allah Ta'ala's path, Allah Ta'ala shall shade (shelter) them just as a vulture shades her nest (while saying this, Hadhrat Ka'b (r.a.a.) demonstrated with his hand how a vulture protects her nest by spreadng her wings on it). They shall never flee from the battlefield." [Abu Nu'aym in his Hilya Vol. 5 Pg. 386.]

According to another narration, Hadhrat Ka'b (r.a.a.) said, "(The Ummah of Rasulullah (s.a.w.) were described in the Torah as) People who shall praise Allah Ta'ala abundantly, who will praise Allah Ta'ala (by saying "Al Hamdu Lillah") during all conditions. They exalt Allah Ta'ala (by saying "Allahu Akbar") when ascending an incline. They will keep track of the sun (to ascertain the correct times of salaah). They shall perform their five daily salaah on time even though it be at a dusty place. They will tie their loincloths at their waists and wash their limbs (when performing wudhu)." [Abu Nu'aym in is Hilya. Another long narration has also been reported from Hadhrat Ka'b (r.a.a.) in the same book.]
