Verily, the guarding and preservation of the Iman is through ‘Taqwa’ or piety. ‘Taqwa’ is the abundance of all that is good. Sayyidina Ali Bin Abi Talib u once said: “Taqwa is having fear of The Exalted, acting upon the revelation, contentment with the little (that one possesses) and preparation for the day of departure.” Allah U has said regarding those who have ‘Taqwa’ or piety:
﴾إِنَّ الْمُتَّقِينَ فِي جَنَّاتٍ وَعُيُونٍ (١٥)آخِذِينَ مَا آتَاهُمْ رَبُّهُمْ إِنَّهُمْ كَانُوا قَبْلَ ذَلِكَ مُحْسِنِينَ﴿
“Indeed, the righteous will be among gardens and springs, Accepting what their Lord has given them. Indeed, they were before that doers of good.” [Surah Adz-Dzariyat: 15-16].
﴾لَمَثُوبَةٌ مِنْ عِنْدِ اللَّهِ خَيْرٌ لَوْ كَانُوا يَعْلَمُونَ﴿ “then the reward from Allah would have been [far] better, if they only knew.”
