Simple steps to heaven:
1- Know the truth: Every one will die, our earthy life is a short deception, escaping fire and eternal heaven should be our goal:
3:185 Every soul shall have a taste of death: And only on the Day of Judgment shall you be paid your full recompense. Only he who is saved far from the Fire and admitted to the garden will have attained the object (of Life): For the life of this world is but goods and chattels of deception.
كُلُّ نَفْسٍ ذَآئِقَةُ الْمَوْتِ وَإِنَّمَا تُوَفَّوْنَ أُجُورَكُمْ يَوْمَ الْقِيَامَةِ فَمَن زُحْزِحَ عَنِ النَّارِ وَأُدْخِلَ الْجَنَّةَ فَقَدْ فَازَ وَما
الْحَيَاةُ الدُّنْيَا إِلاَّ مَتَاعُ الْغُرُورِ
2- Repent and ask God for forgiveness:
3:133 Be quick in the race for forgiveness from your Lord, and for a garden whose width is that (of the whole) of the heavens and of the earth, prepared for the righteous,
وَسَارِعُواْ إِلَى مَغْفِرَةٍ مِّن رَّبِّكُمْ وَجَنَّةٍ عَرْضُهَا السَّمَاوَاتُ وَالأَرْضُ أُعِدَّتْ لِلْمُتَّقِينَ
3- Forget about self-ego, certainty of no afterlife and temptation of arrogance:
7:40 To those who reject Our signs and treat them with arrogance, no opening will there be of the gates of heaven, nor will they enter the garden, until the camel can pass through the eye of the needle: Such is Our reward for those in sin.
إِنَّ الَّذِينَ كَذَّبُواْ بِآيَاتِنَا وَاسْتَكْبَرُواْ عَنْهَا لاَ تُفَتَّحُ لَهُمْ أَبْوَابُ السَّمَاء وَلاَ يَدْخُلُونَ الْجَنَّةَ حَتَّى يَلِجَ الْجَمَلُ فِي سَمِّ الْخِيَاطِ وَكَذَلِكَ نَجْزِي الْمُجْرِمِينَ
4- Attain true faith and true righteousness for fear and respect of God:
7:42 But those who believe and work righteousness,- no burden do We place on any soul, but that which it can bear,- they will be Companions of the garden, therein to dwell (for ever).
وَالَّذِينَ آمَنُواْ وَعَمِلُواْ الصَّالِحَاتِ لاَ نُكَلِّفُ نَفْسًا إِلاَّ وُسْعَهَا أُوْلَـئِكَ أَصْحَابُ الْجَنَّةِ هُمْ فِيهَا خَالِدُونَ
5- Your last step is to inherit heaven, enjoy it:
7:43 And We shall remove from their hearts any lurking sense of injury (envy);- beneath them will be rivers flowing;- and they shall say: "Praise be to Allah, who hath guided us to this (felicity): never could we have found guidance, had it not been for the guidance of Allah. Indeed it was the truth, that the apostles of our Lord brought unto us." And they shall hear the cry: "Behold! The garden before you! Ye have been made its inheritors, for your deeds (of righteousness)."
وَنَزَعْنَا مَا فِي صُدُورِهِم مِّنْ غِلٍّ تَجْرِي مِن تَحْتِهِمُ الأَنْهَارُ وَقَالُواْ الْحَمْدُ لِلّهِ الَّذِي هَدَانَا لِهَـذَا وَمَا كُنَّا لِنَهْتَدِيَ لَوْلا أَنْ هَدَانَا اللّهُ لَقَدْ جَاءتْ رُسُلُ رَبِّنَا بِالْحَقِّ وَنُودُواْ أَن تِلْكُمُ الْجَنَّةُ أُورِثْتُمُوهَا بِمَا كُنتُمْ تَعْمَلُونَ
