Should he pray the present prayer or the prayer he missed?

Question

Praise be to Allah.

The Muslim should maintain the habit of
praying regularly on time, for Allaah praises the believers who, as
He says (interpretation of the meaning):
“And those who guard their Salaah (prayers) well”[al-Ma’aarij 70:34]
If a person has an excuse and he missed a prayer, then he has to make
it up, because the Prophet

(peace and blessings of Allaah be upon him) said: “Whoever forgets a
prayer or sleeps and misses it, the expiation for this sin is to pray
it when he remembers it.” (Narrated by Muslim, al-Masaajid wa
Mawaadi’ al-Salaah, 1103)
If you miss a prayer, then you have to pray that prayer first, then
pray the current prayer; it is not permissible to delay (making up the
missed prayer). It is commonly thought among the people that if a man
misses a fard prayer, he should make it up with the corresponding fard
prayer of the next day, so that if, for example, he missed Fajr on one
day he can only pray it with Fajr on the second day. This is wrong,
and it goes against the teaching of the Prophet

(peace and blessings of Allaah be upon him), in both his words and deeds.
It was narrated that he said: “Whoever forgets a prayer or sleeps and
misses it, then let him pray it when he remembers it.” He did not say,
let him pray it on the following day when the time for that prayer comes,
rather he said, “let him pray it when he remembers it.” With regard
to his actions, when he missed a prayer on one of the days of the campaign
of al-Khandaq, he prayed it before the current prayer, which indicates
that one has to pray the missed prayer and then pray the current prayer.
But if he forgets and prays the current prayer before the missed prayer,
or he was ignorant and did not know (of the ruling), then he prayer
is valid because he has an excuse.(See Fataawa al-Shaykh Ibn ‘Uthaymeen, vol. 12, p. 222)
The hadeeth about the prayer on the day of al-Khandaq was narrated by
al-Nasaa’i from ‘Abd al-Rahmaan ibn Abi Sa’eed from his father, who
said: “The mushrikeen kept us busy on the day of al-Khandaq and distracted
us from praying Zuhr until the sun set. Then the Messenger of Allaah

(peace and blessings of Allaah be upon him) commanded Bilaal to call
the iqaamah for Zuhr prayer, and he prayed it, then he called the iqaamah
for Asr and he prayed it, then he called the adhaan for Maghrib then
he prayed it as he usually prayed it, on time.” (al-Adhaan, 655;
classed as saheeh by al-Albaani in Saheeh al-Nasaa’i, no. 638)
The action of the Prophet

(peace and blessings of Allaah be upon him) indicates that it is obligatory
to pray the missed prayers in the right order. But if there is only
enough time left to pray the current prayer, then he should pray the
current prayer, then pray the ones that came before it.
