Slandering a Sahaabi by saying that he did not know anything about politics

Praise be to Allah.

‘Abd-Allaah ibn ‘Umar (may Allaah be pleased with him) is a great Sahaabi, one of the greatest scholars of the Muhaajireen (those who migrated from Makkah to Madeenah). We should love him and all the Sahaabah, and be pleased with them. It is not permissible to criticize them or any one of them, because the Prophet (peace and blessings of Allaah be upon him) said: “Do not revile my companions, for by the One in Whose hand is my soul, if one of you were to spend the equivalent of Uhud in gold, it would not amount to a mudd of one of them, or half of that.” 

And Allaah is the Source of strength. May Allaah send blessings and peace upon of our Prophet Muhammad and his family and companions. End quote.
