Otherwise everybody who has a phone will be a sinner. We must explain to ourselves that we too do not answer every call, but when we call someone and they do not answer, Satan causes us to get angry. Therefore, keep yourself in a state of peace because anger causes you to form ill opinions about your brothers and utter sentences full of backbiting.
Answer your phone and earn huge reward
It is definitely true that answering everyone’s phone is not an obligatory act, but with the intention of making your Islamic brother happy, ensuring that you protect them from sins like backbiting, and slandering; try your utmost to answer the phone or SMS on the spot because it is highly possible that the caller may be in a serious emergency. If there are such circumstances and you are not able to answer the phone on the spot; then try to call him as soon as possible, and make yourself worthy of rewards in the Hereafter by making him happy.
Look at the incredible virtues of making a Muslim happy. On page 534 of Jannat mayn lay jaanay walay A’maal (the 743-page publication of Maktaba-tul-Madinah, the publishing department of Dawat-e-Islami), it is stated: Sayyiduna Ibn ‘Abbas رَضِیَ الـلّٰـهُ تَعَالٰی عَـنْهُمَا has narrated, ‘In the court of Allah (عَزَّوَجَلَّ), the best deed after offering obligatory deeds is to make the heart of another Muslim happy.’ (Al-Mu’jam-ul-Kabeer, vol. 11, pp. 59, Hadees 11079)
صَلُّوۡا عَلَى الۡحَبِيۡب صَلَّى اللّٰهُ تَعَالٰى عَلٰى مُحَمَّد
Dear Islamic brothers! Except for the mobile phones, there are some other ways as well through which one may have suspicions, though reward can be obtained by having good opinions in many places. Ameer-e-Ahl-e-Sunnat دَامَـتْ بَـرَكَـاتُـهُـمُ الْـعَـالِـيَـه has said: There is no disadvantage of having good opinions and no advantage of having suspicions. Let us listen to the advantages of good opinions and disadvantages of suspicions to develop the habit of forming good opinions.
