English Translation of Al-Quran
[35].Surah Fatir [The Originator of Creation]
Ayat 10. Whosoever desires honor, power and glory then to Allah belongs all honor, power and glory [and one can get honor, power and glory only by obeying and worshipping Allah (Alone)]. To Him ascend (all) the goodly words, and the righteous deeds exalt it (the goodly words i.e. the goodly words are not accepted by Allah unless and until they are followed by good deeds), but those who plot evils, theirs will be severe torment. And the plotting of such will perish.
Tafseer of Surah Fatir Ayat 10. If any do seek for glory and power,- to Allah belong all glory and power. To Him mount up (all) Words of Purity: It is He Who exalts each Deed of Righteousness. Those that lay Plots of Evil, – for them is a Penalty terrible; and the plotting of such will be void (of result). Good and Evil are to be distinguished sharply. No good is ever lost: it goes up to the Throne of Allah. The humblest Good, in word or deed, is exalted to high rank. If man seeks for mere glory and power, there is no such thing apart from Allah. But seeking Allah, we attain the highest glory and power. It is the nature of Evil to work underground, to hide from the Light, to plot against Righteousness: but Evil inevitably carries its own punishment. Its plots must fail miserably. And eventually Evil itself is to be blotted out.
English Translation of Hadith
Hazrat Ibn Abbas (May Allah be pleased with them) reported: The Messenger of Allah ﷺ [SAWW](PBUH) said: “Glorify your Lord in Ruku` (bowing posture) and exert yourself in supplication in prostration. Thus your supplications are liable to be accepted.”
[Muslim Book 004, Chapter 37, Hadith # 970].
Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah ﷺ [SAWW](PBUH) said, “A slave becomes nearest to his Rubb when he is in prostration. So increase supplications while prostrating.”
[Muslim Book 004, Chapter 37, Hadith # 979]
Lesson: as mentioned above in Surah Fatir Ayat 10. Whosoever desires honor, power and glory then to Allah belongs all honor, power and glory” Both the Hadith mentioned above, evidently show that there is greater possibility of acceptance of an invocation which is made in prostration. Therefore, one must do it in the voluntary Salat.
