وَأْمُرْ أَهْلَكَ بِالصَّلَأةِ وَاصْطَبِرْ عَلَيْهَا
...
And enjoin the Salah on your family, and be patient in offering them.
This means to save them from the punishment of Allah by the establishment of the prayer, and you also be patient in performing it.
This is as Allah says,
يأَيُّهَا الَّذِينَ ءَامَنُواْ قُواْ أَنفُسَكُمْ وَأَهْلِيكُمْ نَاراً
O you who believe! Ward off yourselves and your families against a Fire (Hell). (66:6)
Ibn Abi Hatim recorded that Zayd bin Aslam reported from his father that;
he and Yarfa' would sometimes spend the night at Umar bin Al-Khattab's.
Umar had a certain time of night that he would get up and pray. However, sometimes he would not get up for it. Then, we would say, "He is not going to get up like he usually does."
When he would awaken, he would make his family get up as well. He would say,
وَأْمُرْ أَهْلَكَ بِالصَّلَأةِ وَاصْطَبِرْ عَلَيْهَا
(And enjoin the Salah on your family, and be patient in offering them)."
Allah said;
...
لاَا نَسْأَلُكَ رِزْقًا نَّحْنُ نَرْزُقُكَ
...
We ask not of you a provision: We provide for you.
This means that if you establish the prayer, your sustenance will come to you from where you did not expect.
This is as Allah says,
وَمَن يَتَّقِ اللَّهَ يَجْعَل لَّهُ مَخْرَجاًوَيَرْزُقْهُ مِنْ حَيْثُ لاَ يَحْتَسِبُ
And whosoever has Taqwa of Allah, He will make a way for him to get out (from every difficulty). And He will provide him from (sources) he never could imagine. (65:2-3)
Allah also says,
وَمَا خَلَقْتُ الْجِنَّ وَالاِنسَ إِلاَّ لِيَعْبُدُونِ
And I (Allah) created not the Jinn and mankind except that they should worship Me (Alone). until,
إِنَّ اللَّهَ هُوَ الرَّزَّاقُ ذُو الْقُوَّةِ الْمَتِينُ
Verily, Allah is the All-Provider, Owner of Power, the Most Strong. (51:56-58)
Thus, Allah says,
لاَا نَسْأَلُكَ رِزْقًا نَّحْنُ نَرْزُقُكَ
(We ask not of you a provision: We provide for you).
Verily, At-Tirmidhi and Ibn Majah recorded that Abu Hurayrah said that the Messenger of Allah said,
يَقُولُ اللهُ تَعَالى يَا ابْنَ ادَمَ تَفَرَّغْ لِعِبَادَتِي أَمْلَْ صَدْرَكَ غِنىً وَأَسُدَّ فَقْرَكَ وَإِنْ لَمْ تَفْعَلْ مَلَْتُ صَدْرَكَ شُغْلً وَلَمْ أَسُدَّ فَقْرَك
Allah, the Exalted, says, "O son of Adam, perform My worship and I will fill your chest with wealth and fulfill your needs. If you do not do so, then I will fill your chest with toil and I will not fulfill your needs."
It is also reported from Zayd bin Thabit that he heard the Messenger of Allah saying,
مَنْ كَانَتِ الدُّنْيَا هَمَّهُ فَرَّقَ اللهُ عَلَيْهِ أَمْرَهُ وَجَعَلَ فَقْرَهُ بَيْنَ عَيْنَيْهِ وَلَمْ يَأْتِهِ مِنَ الدُّنْيَا إِلاَّ مَا كُتِبَ لَهُ وَمَنْ كَانَتِ الاْخِرَةُ نِيَّتَهُ جَمَعَ لَهُ أَمْرَهُ وَجَعَلَ غِنَاهُ فِي قَلْبِهِ وَأَتَتْهُ الدُّنْيَا وَهِيَ رَاغِمَة
Whoever makes the worldly life his major concern, then Allah will scatter his situation for him (i.e. make it difficult) and his poverty will be placed between his eyes. He will not get from this world anything except that which has already been written for him.
Whoever makes the Hereafter his intention, then his situation will be gathered for him (i.e. made easy) and his wealth will be placed in his heart. The worldly life will come to him anyway (in spite of his not seeking it).
Concerning Allah's statement,
...
وَالْعَاقِبَةُ لِلتَّقْوَى
And the good end is for those who have Taqwa.
This means the good end in this life and in the Hereafter. In the Hereafter the good end will be Paradise for whoever feared Allah.
