Usually many Muslims believe that health, wealth, children and other things are blessings from Allah within itself but Dr. Israr in one of his lectures explained that these things are not always blessings.
He explained that if your wealth attracts you towards things which Allah prohibited, if your wealth makes you invest in haram and do wrong things then wealth and bank balance is not a blessing.
Dr. Israr further explained that nothing is blessing when it comes without the blessing of guidance.
If someone is not guided by Islam then his children will not be a blessing for him rather he will be questioned on the Day of Judgment for their deviation from the commands of Allah.
At the end he said that the biggest blessing which one can get is Quran and the guidance which everyone requires is from Quran which was revealed on Prophet Muhammad (PBUH).
