Hazrat Abu Hurairah(ra) narrates that the Holy Prophet(sa) said, ‘No Muslim suffers any calamity, suffering, pain, discomfort, or anxiety, even as small as the prick of a thorn, but Allah wipes out instead some of his defaults and his sins.’ (Sahih Muslim, Kitab-ul-Birri was-Silah, Babu Thawabil-Mo’mini fi ma yusibuhu min Maradin au Huznin au nahwa dhalik)
In another hadith Hazrat Suhaib Bin Sinan(ra) has related that:
The Holy Prophet(sa) said, ‘Wondrous is the case of a believer; there is good for him in everything, and it is so for him alone. If he experiences something agreeable, he is grateful to God and that is good for him; and if he experiences adversity, he is steadfast and that is good for him because he earns merit for his steadfastness.’ (Sahih Muslim, Kitab-uz-Zuhdi, Babul Mo’mini Amruhu kulluhu Khair)
Sometimes Allah makes His servants go through sufferings related to his children. There is excessive wailing and crying at the death of children, especially among the women. Thanks to Allah, He has granted to the Ahmadiyyah Muslim Jama‘at mothers who are very patient and reconciled to His will. But sometimes there are instances of complaining, especially among the illiterates or those with meagre education. In fact, I have also observed some cases among those with good education that they utter words of ingratitude.
There is a hadith that the Holy Prophet(sa) used to take a pledge from women-Companions(ra) in this respect. The hadith runs as follows:
Hazrat Usaid(ra) relates that he heard from a woman-Companion(ra) who had taken a pledge at the hand of the Holy Prophet(sa) that the pledge included the following: ‘We will not disobey the Holy Prophet(sa), will not tear our faces in wailing, will not raise a hue and cry during mourning, and will not tear our clothes or keep our hair ruffled.’ (Sunano Abi Dawud, Kitab-ul-Jana’ iz, Babun fin-Nauh)
