Surat No. 66, At Tahrim, Ayat No. 6
o مَلَائِكَةٌ غِلَاظٌ شِدَادٌ لَا يَعْصُونَ اللَّهَ مَا أَمَرَهُمْوَيَفْعَلُونَ مَا يُؤْمَرُونَ
O Believers ! save yourselves and your families from a Fire whose fuel is Men and Stones, over which angels are appointed who are stern (and) severe and who do not disobey from executing the Commands they receive from Allah, but they do what they are commanded
Surah No. 20, Ta Ha, Ayat No. 132
وَأْمُرْ أَهْلَكَ بِالصَّلَاةِ وَاصْطَبِرْ عَلَيْهَا لَا نَسْأَلُكَ رِزْقًا نَحْنُ نَرْزُقُكَ وَالْعَاقِبَةُ لِلتَّقْوَى
Enjoin Salat on the members of your family and yourself also observe it strictly. We do not ask any provision of you, for it is We Ourself Who give you provision. And the ultimate good is for piety.
Generally, the head of the family is the father who takes care of his family in all the matters. He always tries to help the family with good financial resources so that the family members can lead a comfortable and tension free life. Allah has commanded that the head of the family must help his family in a manner so that they do not suffer in the Hereafter (Akherat).It is therefore very important that such believers must obtain necessary knowledge of the religion and practice the fundamentals and the other guidelines.
He should then teach his children to say their prescribed Prayers, this will change their attitude, their standard of values, and make them contented with pure provisions and virtuous life in preference to the life of sin and luxury." This will create piety in them which will bring about true success in this world and in the Hereafter."
The best time of holding meetings with the family members is immediately after the dinner. He should also make them agree to gradually practice the guidelines given by Allah. Once they join him to practice the religious guidelines then the role of the head of the family is over and he should pray to Allah to shower His blessings on them. Thereafter it will depend on the individual family members to lead such a life which leads them to save themselves from that Blazing Fire in the Hereafter.
