يعلم ما بين أيديهم وما خلفهم ولا يشفعون إلا لمن ارتضى وهم (21:28) بالانجليزي

(21:28) He knows whatever is before them and also whatever is hidden from them; they "do not intercede for anyone except for the one for whom Allah pleases to hear a plea, and they live in awe of Him *27

Tafseer Abu-al-A'la Maududi

Page 324 English Traditional

*27) These two verses refute the two reasons for which the mushriks had made the angels their deities:
(1) They took them for the offspring of Allah.
(2) They thought that if they worshipped the angels, they would be so pleased that they would intercede with Allah on their behalf. (See X:18; XXXIX:3).
In this connection, it should also be noted that the Qur'an refutes the doctrine of intercession of the mushriks, saying, that their so-called intercessors are not qualified to intercede for anyone. This is so' because they have no knowledge of the hidden things, whereas Allah knows all that is hidden from or open to them. Therefore, the angels or Prophets or saints shall be allowed intercession only with the prior permission of Allah. As Allah alone has the power to hear or accept intercession, none else is entitled to divine worship or rights. For further details, please sec Ta Ha (XX): E. N.'s 85-86.
