All perfect praise be to Allaah, The Lord of the worlds. I testify that there is none worthy of worship except Allaah and that Muhammad is His slave and Messenger.
We have previously received a similar question from you and answered it in fatwa 319621.
In any case, a Muslim is responsible for what he knows, but he is not required to investigate what he does not know to be held responsible for it.
Imaam Maalik narrated in Al-Muwatta’ that once ‘Umar ibn Al-Khattaab
was among a group that included ‘Amr ibn Al-'Aas
until they came upon a pond. ‘Amr ibn Al-'Aas asked the owner of the pond, “Have the beasts of prey discovered your pond?" Thereupon, ‘Umar ibn Al-Khattaab interrupted, “O owner of the pond! Do not inform us; since the people drink after the wild beasts and the wild beasts after the people.”
Therefore, just seeing a picture of a person whose name is ‘Abdullaah does not entail that one is obliged to pick it up, unless he sees the name of Allaah or other sacred text written on it that requires preserving it from being treated with disrespect. Nevertheless, before a person sees the name, he is not liable and is free from any obligation.
The statement of Ad-Dardeer applies to what one actually saw and not what he did not see.
Allaah knows best.
