Sheding tears shouldn’t be just due to the huge problems one may come across. Noticing and payning attention to the beloved one and building your relationship with him is sufficient that your heart goes out for him and you shed tears.Weeping in solitude is concealed by Allah from the angels whose names are mentioned in the Holy Quran as the great writer angels.The angels are asked to leave the servant alone and the servant disappears from them and is put under the shelter of Allah Almighty.
