What is the correct way of offering salat ul hajat?
بِسْمِ اللهِ الرَّحْمنِ الرَّحِيْم
In the name of Allah, the Most Gracious, the Most Merciful
The way of performing Salat Al-Hajat is explained in the following hadith:
Abdullah ibn Abi Awfa (Allah be pleased with him) relates that the Messenger of Allah (Allah bless him and give him peace) said, “Whoever has a need with Allah, or with any human being, then let them perform ritual ablutions well and then pray two rakats. After that, let them praise Allah and send blessings on the Prophet (Allah bless him and give him peace). After this, let them say,
لا إِلَهَ إِلا اللَّهُ الْحَلِيمُ الْكَرِيمُ
سُبْحَانَ اللَّهِ رَبِّ الْعَرْشِ الْعَظِيم
الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِين
أَسْأَلُكَ مُوجِبَاتِ رَحْمَتِكَ وَعَزَائِمَ مَغْفِرَتِكَ وَالْغَنِيمَةَ مِنْ كُلِّ بِرٍّ وَالسَّلامَةَ مِنْ كُلّ إِثْمٍ
لا تَدَعْ لِي ذَنْبًا إِلا غَفَرْتَهُ وَلا هَمًّا إِلا فَرَّجْتَهُ وَلا حَاجَةً هِيَ لَكَ رِضًا إِلا قَضَيْتَهَا يَا أَرْحَمَ الرَّاحِمِينَ
There is no god but Allah, the Clement and Wise.
There is no god but Allah, the High and Mighty.
Glory be to Allah, Lord of the Tremendous Throne.
All praise is to Allah, Lord of the worlds.
I ask you (O Allah) everything that leads to your mercy, and your tremendous forgiveness, enrichment in all good, and freedom from all sin.
Do not leave a sin of mine (O Allah), except that you forgive it, nor any concern except that you create for it an opening, nor any need in which there is your good pleasure except that you fulfil it, O Most Merciful!”
Only Allah knows best
