Will a Muslim be rewarded for spending on building?

It was narrated from Anas ibn Maalik that the Messenger
of Allaah

(peace and blessings of Allaah be upon him) said: “”Every building will
bring bad consequences to the one who built it, except that (which is
necessary).” 

(Narrated by Abu Dawood, 5237; Ibn Maajah, 4161) 

This hadeeth was classed as saheeh by al-Albaani in
al-Silsilah al-Saheehah, 2830. 

It was narrated that Khabbaab ibn al-Aratt said: “I heard
the Messenger of Allaah

(peace and blessings of Allaah be upon him) say: ‘A man will be rewarded
for all of his spending, except (spending on) dust – or he said, on
building.’” 

(Narrated by al-Tirmidhi, 2483; Ibn Maajah, 4163). 

This hadeeth was classed as saheeh by Shaykh al-Albaani
in al-Silsilah al-Saheehah, 2831. 

Shaykh al-Albaani said: 

Know that what is meant in this hadeeth and the previous
hadeeth – and Allaah knows best – is when a Muslim is too concerned
with building and buikds more than he needs. There is no doubt that
what is necessary varies according to the size of the builder’s family,
whether it is large or small, and whether he entertains guests or not.
In that regard it is similar to the saheeh hadeeth, “A bed for the man,
a bed for his wife, a bed for their guest, and the fourth is for the
Shaytaan.” (Narrated by Muslim, 6/146 and others; also narrated in Saheeh
Abi Dawood). 

Hence al-Haafiz said, after quoting this hadeeth and
others: 

“These are all to be interpreted as referring to things
that are needed in order to live a settled life, and to that which offers
protection against heat and cold.” 

Then he spoke of some people who gave the false impression that all
kinds of building are sinful, and he commented on that by saying: 

“That is not the case, rather it is subject to further
explanation. Not everyone who builds more than he needs is necessarily
guilty of sin… in some cases, building may bring reward, such as something
which benefits people other than the builder – this brings the builder
reward. And Allaah knows best.
