Wudu or Ghusl [ritual bath] anytime during the day or night I offered Salah as much as Allah Almighty wills me to do so. (Sahih Muslim, pp. 1025, Hadees 2458)

A great thinker of Ummah, ‘Allamah Mufti Ahmad Yar Khan Na’eemi رَحْمَةُ اللهِ تَعَالٰی عَلَيْه has also mentioned another meaning of the above-mentioned blessed Hadees that the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم saw all these things physically in Mi’raaj, but he صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم asked this question some other day after Fajr Salah. He رَحْمَةُ اللهِ تَعَالٰی عَلَيْه further said: Sayyiduna Bilal’s entry into Paradise before the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم is like the entry of the servant who walks in front of his king.

Remember! During the night of Mi’raaj, neither did Sayyiduna Bilal رَضِىَ اللهُ تَعَالٰی عَـنْهُ accompany the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم to Paradise nor did he                 رَضِىَ اللهُ تَعَالٰی عَـنْهُ was blessed with Mi’raaj, but rather the Holy Nabi صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم saw the event which will happen after the Judgement Day. The Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم will enter Paradise before [all] creation in a way that Sayyiduna Bilal رَضِىَ اللهُ تَعَالٰی عَـنْهُ will be in front of him as a servant.

We have learned some rulings from it. Firstly, Allah عَزَّوَجَلَّ made the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم aware of the consequences of people such as who will be sent to Paradise and who will be sent to Hell, what will be the level of the one who will be sent to Paradise and the one who will be sent to Hell. Secondly, the blessed ears of the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم heard and the blessed eyes saw the events which will happen after hundreds of thousands of years. This event will happen after many hundreds of thousands of years after that date. But may I be sacrificed on the blessed ears which are listening to them today. Thirdly, the way a person lives his life in this world, in the same way he will be in the Hereafter, as Sayyiduna Bilal رَضِىَ اللهُ تَعَالٰی عَـنْهُ spent his life serving the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم in the world so he رَضِىَ اللهُ تَعَالٰی عَـنْهُ will also be raised as a servant in the Hereafter. (Mirat-ul-Manajih, vol. 2, pp. 300)

O devotees of companions and Ahl-e-Bayt! Have you heard! By his great knowledge of Ghayb, our Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم heard the sound [that will be] produced by the feet of Sayyiduna Bilal رَضِىَ اللهُ تَعَالٰی عَـنْهُ on the Judgement Day hundreds of thousands of years before.
