Mishkat al-Masabih 198

‘Abdallah b. ‘Amr reported God’s messenger as saying, “God does
not take away knowledge by removing it from men, but takes it away
by taking away the learned, so that when He leaves no learned man, men
will take ignorant men as leaders. Causes will be presented to them
and they will pass judgement without knowledge, erring and leading
others into error.” (Bukhari and Muslim.)

Anas said that when the Prophet made a statement he repeated it
three times so that it would be understood, and that when he met a company and gave them a salutation he did it three times. Bukhari
transmitted it.

He also reported God’s messenger as saying, “The first person to
be judged on the day of resurrection will be a man who died as a martyr.
He will be brought forward, and after God has reminded him of the
favour He showed him and the man acknowledges it, He will ask,
‘What did you do to show gratitude for it?’ The man will reply, ‘I
fought for Thy cause till I was martyred.’ God will say, ‘You lie. You
fought that people might call you courageous, and they have done so.’
Command will then be issued about him, and he will be dragged on his
face and thrown into hell. Next a man who has acquired and taught
knowledge and read the Qur’an will be brought forward, and after God
has reminded him of the favour He showed him and the man acknowledges
it, He will ask, ‘What did you do to show gratitude for it?’ The man
will reply, ‘I acquired and taught knowledge and read the Qur’an for
Thy sake.’ God will say, 'You lie. You acquired knowledge that people
might call you learned, and you read the Qur’an that they might call
you a reader, and they have done so.’ Command will then be issued
about him, and he will be dragged on his face and thrown into hell.
Next a man whom God has made affluent and whom He has given all kinds
of property will be brought forward, and after God has reminded him
of the favour He showed him and the man acknowledges it, He will ask,
‘What did you do to show gratitude for it?’ The man will reply, ‘I
have not neglected to give liberally for Thy sake to all the causes
approved by Thee for this purpose.’ God will say, ‘You lie. You did
it that people might call you generous, and they have done so.’ Command will then be issued about him, and he will be dragged on his face
and thrown into hell.” Muslim transmitted it.
