Why is that when we ask, Allah SWT does not grant us?

I received an email from the school's parent mailing list and it contains the following reminders for us.

Has Your Heart Died?

Abu Is’haq Ibrahim was once passing through a bazaar in Basrah when he was asked: “O Abu Is’haq, verily Allah has declared ‘Ask Me and I will grant you your requests.’ Why is that when we ask, He does not grant us?” Abu Is’haq replied: “It’s because your hearts have become dead, and this is due to ten reasons”.

Ten reasons why hearts die?

1. You have known who Allah SWT is, yet have not fulfilled your duties.
2. You have read the Qur’an, yet have not practiced upon it.
3. You have proclaimed the love of the Messenger, yet you have not followed his traditions (sunnah).
4. You have declared that satan is your enemy, yet you have stood with him.
5. You have declared your desire for paradise, yet you have done nothing to achieve it.
6. You have declared your fear of Hell, yet you have done nothing to escape it.
7. You have proclaimed that there is no escape from death, yet you do not prepare for it.
8. You have indulged in searching the faults of others, yet you have not looked for your own faults.
9. You have enjoyed all the blessings and bounties, yet you do not give Him due praise for it.
10. You have buried your dead but you have taken no lesson from it.
