[Machine] On the authority of the Prophet ﷺ , he said: When the caller calls for prayer, the gates of heaven are opened and the supplication is answered. So, whoever is inflicted with distress or hardship, let them be cautious of the caller. And when he says: "Allahu Akbar", say: "Allahu Akbar", and when he says: "Ashhadu an la ilaha illa Allah", say: "Ashhadu an la ilaha illa Allah", and when he says: "Hayya 'ala as-Salah", say: "Hayya 'ala as-Salah", and when he says: "Hayya 'ala al-Falah", say: "Hayya 'ala al-Falah". Then, say: "Allahumma rabba hadhihid da'watit-tammati, salatiqa al-mustajabati, mustajabatan laha, da'wati al-haqi, wa kalimati at-taqwa, ahina 'alayha wa amitna 'alayha, wa ab'athna 'alayha, waj'alna min khayri ahliha ahyaa wa amwatan". Then, ask Allah for your need.  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا نَادَى الْمُنَادِي فُتِحَتْ أَبْوَابُ السَّمَاءِ وَاسْتُجِيبَ الدُّعَاءُ فَمَنْ نَزَلَ بِهِ كَرْبٌ أَوْ شِدَّةٌ فَلْيَتَحَيَّنِ الْمُنَادِي فَإِذَا كَبَّرَ كَبِّرُوا وَإِذَا تَشَهَّدَ تَشَهَّدُوا وَإِذَا قَالَ حَيَّ عَلَى الصَّلَاةِ قَالَ حَيَّ عَلَى الصَّلَاةِ وَإِذَا قَالَ حَيَّ عَلَى الْفَلَاحِ قَالَ حَيَّ عَلَى الْفَلَاحِ ثُمَّ يَقُولُ اللَّهُمَّ رَبَّ هَذِهِ الدَّعْوَةِ الصَّادِقَةِ الْمُسْتَجَابَةِ الْمُسْتَجَابُ لَهَا دَعْوَةِ الْحَقِّ وَكَلِمَةِ التَّقْوَى أَحْيِنَا عَلَيْهَا وَأَمِتْنَا عَلَيْهَا وَابْعَثْنَا عَلَيْهَا وَاجْعَلْنَا مِنْ خِيَارِ أَهْلِهَا أَحْيَاءً وَأَمْوَاتًا ثُمَّ يَسْأَلُ اللَّهَ حَاجَتَهُ «»
