اللَّحْمُ يُنْبِتُ اللَّحْمَ وَ مَنْ تَرَكَ اللَّحْمَ أَرْبَعِينَ يَوْماً سَاءَ خُلُقُهُ وَ مَنْ سَاءَ خُلُقُهُ فَأَذِّنُوا فِي أُذُنِهِ.
“Abu ‘ Abd Allah (a.s.), has said, ‘Meat grows meat and one who does not eat meat for forty days his manners change to worse, you must say Adhan in the ears of one whose manners change to worse.’”
قُلْتُ لِأَبِي الْحَسَنِ الرِّضَا ع إِنَّ النَّاسَ يَقُولُونَ إِنَّ مَنْ لَمْ يَأْكُلِ اللَّحْمَ ثَلَاثَةَ أَيَّامٍ سَاءَ خُلُقُهُ فَقَالَ كَذَبُوا وَ لَكِنْ مَنْ لَمْ يَأْكُلِ اللَّحْمَ أَرْبَعِينَ يَوْماً تَغَيَّرَ خُلُقُهُ وَ بَدَنُهُ وَ ذَلِكَ لِانْتِقَالِ النُّطْفَةِ فِي مِقْدَارِ أَرْبَعِينَ يَوْماً.
‘They have spoken lies. However, one who does not eat meat for forty days his manners change and it is because the seed (sperm) transfers (from one stage of development to another) within the duration of forty days.”
قَالَ رَسُولُ اللَّهِ ص مَنْ أَتَى عَلَيْهِ أَرْبَعُونَ يَوْماً وَ لَمْ يَأْكُلِ اللَّحْمَ فَلْيَسْتَقْرِضْ عَلَى اللَّهِ عَزَّ وَ جَلَّ وَ لْيَأْكُلْهُ.
“Abu ‘Abd Allah (a.s.), has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, ‘One with whom forty days pass and has not eaten meat should borrow, on the credit of Allah, most Majestic, most Glorious, to buy meat to eat.’”
