Truthfulness in the Quran

1.     وَإِن كُنتُمْ فِي رَيْبٍ مِّمَّا نَزَّلْنَا عَلَىٰ عَبْدِنَا فَأْتُوا بِسُورَةٍ مِّن مِّثْلِهِ وَادْعُوا شُهَدَاءَكُم مِّن دُونِ اللَّهِ إِن كُنتُمْ صَادِقِينَ ‎﴿البقرة: ٢٣﴾‏

 And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah he like thereof and call upon your witnesses other than Allah, if you should be truthful. Surah Al Baqara 23.

2.     وَعَلَّمَ آدَمَ الْأَسْمَاءَ كُلَّهَا ثُمَّ عَرَضَهُمْ عَلَى الْمَلَائِكَةِ فَقَالَ أَنبِئُونِي بِأَسْمَاءِ هَـٰؤُلَاءِ إِن كُنتُمْ صَادِقِينَ ‎﴿البقرة: ٣١﴾‏

‏  And He taught Adam the names - all of them. Then He showed them to the angels and said, Inform Me of the names of these, if you are truthful. " Surah Al Baqara 31 

3.     قُلْ إِن كَانَتْ لَكُمُ الدَّارُ الْآخِرَةُ عِندَ اللَّهِ خَالِصَةً مِّن دُونِ النَّاسِ فَتَمَنَّوُا الْمَوْتَ إِن كُنتُمْ صَادِقِينَ ‎﴿البقرة: ٩٤﴾‏

Quran verses about Dawah

مَا عَلَى الرَّسُولِ إِلَّا الْبَلَاغُ وَاللَّهُ يَعْلَمُ مَا تُبْدُونَ وَمَا تَكْتُمُونَ (99)

Not upon the Messenger is [responsibility] except [for] notification. And Allah knows whatever you reveal

and whatever you conceal. (Al Maidah 5:99)

Since in the Qur’an the word “da`wah” appears numerous times, only those verses that speak of or imply the preaching and spreading of Islam are dealt here. The following lines of the Qur’an contain the word “da`wah” with this connotation.

وَإِذَا سَأَلَكَ عِبَادِي عَنِّي فَإِنِّي قَرِيبٌ ۖأُجِيبُ دَعْوَةَ الدَّاعِ إِذَا دَعَانِۖفَلْيَسْتَجِيبُوا لِي وَلْيُؤْمِنُوا بِي لَعَلَّهُمْ يَرْشُدُونَ ‎﴿١٨٦﴾‏

If some servants of mine asked you about Me, I am indeed close and I respond to the call of a suppliant if he calls upon Me. So let them respond to My (invitation), so that they believe in Me and may be on the right side.  (Al-Baqarah 2:186)

ادْخُلُوا الْجَنَّةَ 

 1 .    كُلُّ نَفْسٍ ذَائِقَةُ الْمَوْتِ وَإِنَّمَا تُوَفَّوْنَ أُجُورَكُمْ يَوْمَ الْقِيَامَةِ فَمَن زُحْزِحَ عَنِ النَّارِ وَأُدْخِلَ الْجَنَّةَ  فَقَدْ فَازَ وَمَا الْحَيَاةُ الدُّنْيَا إِلَّا مَتَاعُ الْغُرُورِ ‎﴿آل عمران: ١٨٥﴾

Every soul will taste death, and you will only be given your [full] compensation on the Day of Resurrection. So he who is drawn away from the Fire and admitted to Paradise has attained [his desire]. And what is the life of this world except the enjoyment of delusion. Quran 3 Al Imran verse 180

2 .   أَهَـٰؤُلَاءِ الَّذِينَ أَقْسَمْتُمْ لَا يَنَالُهُمُ اللَّهُ بِرَحْمَةٍ ادْخُلُوا الْجَنَّةَ  لَا خَوْفٌ عَلَيْكُمْ وَلَا أَنتُمْ تَحْزَنُونَ ‎﴿الأعراف: ٤٩﴾‏

[Allah will say], "Are these the ones whom you [inhabitants of Hell] swore that Allah would never offer them mercy? Enter Paradise , [OPeople of the Elevations]. No fear will there be concerning you, nor will you grieve.

Quran Surah 7 Al Araf verse 49

Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “Verily, Allah does not look at your appearance or wealth, but rather he looks at your hearts and actions.”

Introduction

All praise is due to Allah, we praise Him and seek His aid and forgiveness. We seek refuge in Allah from the evils of our own souls and the wickedness of our deeds. He whom Allah guides, none can misguide, and he whom He misguides, none can guide. I bear witness that there is no god but Allah, alone, without partner, and I bear witness that Muhammad is His servant and Messenger. This is a message entitled (Thirty Reasons for Entering Paradise) in which I have collected a number of authentic verses and hadiths that mention deeds that are a reason by the grace of Allah for the one who does them to enter Paradise. However, this does not mean that these deeds guarantee that any person who does them will enter Paradise, regardless of his belief, because Paradise is only entered by a believer. If a disbeliever or polytheist does some or all of these deeds, they will not benefit him and will not enter Paradise, because Allah, the Most High, says:

وَلَقَدْ أُوحِيَ إِلَيْكَ وَإِلَى الَّذِينَ مِن قَبْلِكَ لَئِنْ أَشْرَكْتَ لَيَحْبَطَنَّ عَمَلُكَ وَلَتَكُونَنَّ مِنَ الْخَاسِرِينَ  ‎﴿٦٥﴾‏ 

And it was already revealed to you and to those before you that if you should associate [anything] with Allah, your work would surely become worthless, and you would surely be among the losers." [Az-Zumar: 65]

And Allah, the Most High, says about the disbelievers:

وَقَدِمْنَا إِلَىٰ مَا عَمِلُوا مِنْ عَمَلٍ فَجَعَلْنَاهُ هَبَاءً مَّنثُورًا  ‎﴿٢٣﴾‏

 And We will regard what they have done of deeds and make them as dust dispersed. [Al-Furqan: 23]

Therefore, Islam is the first condition necessary for the acceptance of any deed.

As for the second condition  that must accompany any deed in order for it to be acceptable to Allah, the Most High, is sincerity in the deed for the sake of Allah, the Most High, meaning that the one who does the deed must intend it for the sake of Allah, the Most High, without associating any other creature with him in his intention. The evidence is the saying of the Prophet (peace and blessings of Allaah be upon him): “Allah does not accept any action except that which is sincere and done for His sake.” [Narrated by al-Nasa’i, Saheeh al-Jami’ 1856]

قال النبي صلى الله عليه وسلم: إن الله تعالى لا يقبل من العمل إلا ما كان خالصا وابتغي به وجهه [ رواه النسائي ، صحيح الجامع 1856]

As for the third condition  for the acceptance of an action, it is following the Messenger (peace and blessings of Allaah be upon him), so we have limited ourselves in this message to the authentic hadeeths that are proven from the Messenger (peace and blessings of Allaah be upon him).

وَمَن يُطِعِ اللَّهَ وَالرَّسُولَ فَأُولَٰئِكَ مَعَ الَّذِينَ أَنْعَمَ اللَّهُ عَلَيْهِم مِّنَ النَّبِيِّينَ وَالصِّدِّيقِينَ وَالشُّهَدَاءِ وَالصَّالِحِينَ  ۚ وَحَسُنَ أُولَٰئِكَ رَفِيقًا ‎﴿٦٩﴾‏

And whoever obeys Allah and the Messenger - those will be with the ones upon whom Allah has bestowed favor of the prophets, the steadfast affirmers of truth, the martyrs and the righteous. And excellent are those as companions. Surah An-Nisa :69
