Nine things will cause forgetfulness...
Nine things will cause forgetfulness: eating sour apples; eating coriander and cheese; eating remainders of mice; urinating in stagnant water; reading the writings on the tombs; going in between two women; killing lice; and cupping at the pit of the head.” [13] فَقالَ عَلَيْهِ السَّلامُ: وَأمَّا ما ذَكَرْتَ مِنْ أَمْرِ الذِّكْرِ وَالنِّسْيانِ، فَإِنَّ قَلْبَ الرَّجُلَ فِي حُقٍّ وَعَلَى الحُقِّ طَبَقٌ، فَإِنْ صَلَّى الرَّجُلُ عِنْدَ ذلِكَ عَلَى مُحَمَّد وَآلِ مُحَمَّدٍ صَلاة تامَّةً، انْكَشَفَ ذلِكَ الطَّبَقُ عَنْ ذلِكَ الحَقِّ، فَأَضاءَ القَلْبُ وَذَكَرَ الرَّجُلُ ما كانَ نَسِيَ، فَإِنْ [هُوَ] لَمْ يُصَلِّ عَلَى مُحَمَّدٍ وَآلِ مُحَمَّدٍ أَوْ نَقَصَ مِنَ الصَّلاةِ عَلَيْهِم، انْطَبَقَ ذلِكَ الطَّبَقُ عَلَى ذلِكَ الحَقِّ، فَأَظْلَمَ القَلْبَ وَنَسِيَ الرَّجُلُ ما كانَ ذَكَرَهُ And regarding what you asked about remembering and forgetting, there is a cavity in a man’s heart over which there is a plate.
When a man perfectly expresses ‘مُحَمَّد وَآلِ مُحَمَّدٍ صَلاة تامَّةً’ that “Blessings be Upon Muhammad -saww and the Household of Muhammad -asws ”, this plate will be removed from that cavity. Then the heart will be illuminated and man will remember what he had forgotten. However, if one does not express that ‘Blessings be Upon Muhammad -saww and the Household of Muhammad -asws ’, or imperfectly expresses the blessings upon them -asws , this plate will totally cover that cavity.
Then the heart will be in darkness and man will forget what he had remembered.
